2 servers, put 5 clients on each 
server.) Circumvent the file sys-
tem if possible, i.e. access raw 
disk if your application allows, 
as many dbms's do.


The choice of network physical 
layer should be considered care-
fully. FDDI, in reality, only in-
creases NFS speeds by about a 
factor of 2. In tuning a network 
look at the number of nfsd's, 
MAXUSERS, and use nfsstat 
and nfswatch to find out how 
your network is performing, 
where problems might be.


Programmers can make their ap-
plications run faster by using -
O4 and -fast compiler switches. 
Beware: -O4 does not work for 
device drivers (loop counters in 
registers are ignored) and IEEE 
floating point precision may be 
degraded. Profile code and find 
out where the application spends 
the most time--use assembly to 
speed those parts up if neces-
sary. Use dynamic linking.


Third parties (Interphase, Lega-
to) offer NFS accelerators. Other 
NFS improvements come from 
increasing MAXUSERS to 
greater than 64 and decrease 
blocks of data to 4K. Optimize 
the number of biod's, especially 
if socket overflows are a prob-
lem. Reduce the number of sym-
bolic links. Look at the number 
of NBUFS in the kernel (buffer 
cache buffers). It should be 112 
for a system with more than 4 
disks and 64 for a system with 
less than 4 disks. Do not increase 
NBUFS to more than 112 since 
Sun has gotten some funky er-
rors by trying that.


Pat made his notes and some re-
lated papers available to all who 
wanted to copy them. Contact 
Pat at the local Sun office if you 
are interested. at the Sun office if 
you are interested.


 And don't forget to send your 
dues if you haven't paid since 
Sept. 1990.

 Conferences


 The Sun User Group sponsors 
two conferences per year, in 
June and in December. The De-
cember Conference has a large 
vendor exhibit. Each Confer-
ence features a day of tutorials 
and several days of technical 
sessions. The conferences are 
attended by members from 
around the world: the 1990 
Conference in San Jose was at-
tended by over 4000 individu-
als from 22 countries, plus 43 
of the fifty United States and 
the District of Columbia.


 Forthcoming conferences are:


 	Atlanta, GA, June 17-19, 1991


 	San Jose, CA, December 7-10, 
1991


 	Washington, DC, June 1992


 	San Jose, CA, December 1992


 The Sun User Group is dedi-
cated to keeping in the fore-
front of Sun and Sun-licensed 
technology. The tutorials re-
flect the changing interests and 
demands of our technical and 
professional members. 


Software Library


 The Sun User Group makes 
available public domain (un-
supported, donated) software. 
In the past, there have been 
software tapes; in 1991, keep-
ing in the technological fore-
front, SUG is issuing a CD-
ROM. Send email for further 
information.


README Newsletter


The Sun User Group publishes 
a quarterly newsletter, contain-
ing useful articles; User Group 
news; and Sun Microsystems 
and third-party vendor infor-
mation. Submissions are en-
couraged, and may be sent to


 readme@sug.org . 1990 issues 
included articles concerning Su-
peruser Privileges and about Do-
mains and Networks.


Local User Groups


 One of the ways of getting to 
know your colleagues is through 
a local user group. Local User 
Groups (LUGs) exist throughout 
the world. Currently, there are 
LUGs in 29 states and 18 coun-
tries. The Sun User Group sup-
ports these local groups with list-
ings, literature, a mailing list 
(LUG-NUTS), and organization-
al assistance. Several internation-
al


 LUGs have entered into formal 
arrangements with the Sun User 
Group to ensure that their mem-
bers receive README and other 
benefits.


 Get involved with your local 
user group.

 CD-ROM is causing a revolution 
in software distribution for the 
UNIX workstation market. The 
current leading media, magnetic 
tape, is being discarded by compa-
nies such as Sun Microsystems, 
Hewlett Packard, Intergraph, DEC, 
IBM, etc. in favor of CD-ROMs.


 To encourage their customer base 
to acquire CD-ROM drives, a vari-
ety of programs have been insti-
tuted, which include bundling 
drives with most server models 
and developer systems or offering 
a drive free with a software sup-
port contract. Other programs pro-
vide incentives to purchase a drive 
by simply lowering prices for CD-
ROM based software distribu-
tions.


 Note that one CD-ROM drive on 
an NFS network will give every-
one access to the CD-ROMS. 
Companies such as SCO, Interac-
tive, NeXT, Apollo, Silicon 
Graphics, Data General, Motoro-
la, AT&T and others have ISO 
9660 CD-ROM drivers available 
and are formulating their own 
CD-ROM strategies. To date, Sun 
Microsystems is by far the most 
aggressive pursuer of CD-ROM; 
almost every SPARCstation net-
work has access to at least one 
SunCD drive. 


 Why The Shift To CD-ROMS?


 The potential savings are huge. 
The break-even point for replicat-
ing 60 MB quarter-inch cartridge 
(QIC) tapes versus CD-ROM is 
just 50 copies. At 1000 disc cop-
ies, media reproduction savings 
for CD-ROM compared to QIC


 tapes can exceed $20,000. 


 Cost Of CD-ROM Reproduction


 The cost of disc reproduction is 
currently $1.30 to $2 with master-
ing charges ranging between $800 
and $2100. Prices depend upon 
turn around time and quantity of 
discs replicated along with other 
variables. The mastering facilities 
usually include two color art on 
the CD and a plastic jewel box at 
no extra charge. (Mastering is the 
creation of a metal mold that is 
used in replicating discs.) 


 Aside from being inexpensive, 
the media is reliable, durable, 
high capacity (680MB), light and 
randomly accessible. Mean-
while, CD-ROM mastering and 
replication costs are becoming 
lower due to the excess capacity 
that exists in the CD Audio plants 
where the CD-ROMs are pressed.


 The ROCK RIDGE Interchange 
Protocols


 In March 1991, 16 companies an-
nounced support for the ROCK 
RIDGE Interchange Protocols, a 
framework for adding POSIX 
support to the international CD-
ROM standard ISO 9660. With-
out breaking the standard in any 
way, Rock Ridge allows Unix ap-
plications and other operating 
systems' applications to run di-
rectly off the disc without the 
need for modification of any files. 


 The National Institute of Stan-
dards and Technology (NIST) is 
currently reviewing the exten-
sions for inclusion in a Federal In-
formation Processing Standard 
(FIPS). Simultaneously, the ma-
jor workstation companies are 
adding these extensions to their 
CD-ROM drivers, in effect creat-
ing a defacto open standard. The 
ISO 9660 advantage is that


 software publishers can deliver 
multiple binaries of their software 
on a single CD-ROM in a format 
that most every computer in the 
market has a capacity to read. 


 Simply, CD-ROM is a software 
marketer's dream. How else could 
a digital, multimedia, software 
demo be possible that includes 
hypertext, documentation, full 
motion video and software bina-
ries for multiple computer plat-
forms on a $2 disc? 


 Software marketers should ap-
preciate the fact that CD-ROMs 
680 MB capacity allows them to 
put multiple applications on one 
disc. With license management 
packages available from 3rd par-
ties along with data encryption 
schemes, a publisher can maintain 
complete control over the use of 
software or information on his 
CD-ROM. 


 How Simple Is It To 
Create A CD-ROM?


 A software vendor simply 
chooses the data set he wants on a 
disc and arranges it into a direc-
tory structure. NFS- exported file 
systems may be included. Files 
that must be changed during exe-
cution or installation of your soft-
ware should be copied off the 
CD-ROM to a hard disk before 
use. Each file's new location and 


all references to it should be iden-
tified using a reliable absolute ad-
dress or specified relative to its lo-
cation on the CD-ROM. After 
giving special attention to as-
signing reasonable ownership 
and permissions for the files to 
be distributed you are ready for 
formatting the finalized directo-
ry structure as an ISO 9660 im-
age. 


 Simple as preparing a CD-
ROM is, the ISV generally 
needs a high level of quality 
control over this important pro-
cess. In-house CD-ROM prepa-
ration with Young Minds CD-
ROM publishing software 
"Makedisc", achieves this ob-
jective. The advantages of in-
house quality control along with 
the speed and convenience in 
getting product to market can 
not be matched by a service bu-
reau. Working with a service 
bureau is normally a slow and 
expensive process due to the 
verification process needed for 
testing the layout and format-
ting of a disc. 


 "MAKEDISC", Young Minds 
ISO 9660/Rock Ridge format-
ting software is the ISV's core 
CD-ROM technology. It creates 
a finished CD-ROM disc image


 that can be sent to a CD press-
ing facility on tape or other elec-
tronic media for mastering and 
replication. A CD-ROM image 
can be tested before mastering 
by placing it in a hard disk par-
tition and mounting it with the 
workstation's CD-ROM driver 
to emulate functionality of a 
real CD-ROM! 


 This UNIX program offers a 
major advantage over MS-DOS 
systems in that no dedicated 
hardware is required. The other 
major advantage is that all Unix 
style names and symbolic links 
are converted to ISO 9660 for-
mat automatically and can be 
read by Unix platforms that do 
not currently have their Rock 
Ridge drivers implemented. 
Makedisc solves the publisher's 
CD-ROM formatting night-
mares with one simple to learn


 Unix command. 


 YOUNG MINDS, INC., is pro-
viding the Unix-based CD-
ROM formatting software used 
by the majority of the Unix 
ISV's and Unix computer com-
panies creating CD-ROMs to-
day. Today, most ISO 9660 CD-
ROMs distributed in the Unix 
market are formatted using 
Young Minds


 software. A partial client list in-
cludes Highland Software, LSI 
Logic, NeXT, Hewlett Packard, 
Tiger Media, McDonnell Dou-
glas, Island Graphics, Harvard 
University, U.C Berkeley, Inter-
leaf, JPL, CALS, NIST, Com-
puter Signal and Sony, along 
with other major universities, 
Unix workstation manufacturers 
and ISV's. "Makedisc" is en-
abling the Unix CD-ROM soft-
ware distribution revolution to 
happen. 


 "Makedisc" runs on all Sun 
workstations and on most other 
major Unix platforms including 
Hewlett Packard HP/UX(TM), 
88open(TM), Apollo Do-
main(TM), DEC Ultrix(TM), 
NeXT(TM) and IBM RS/
6000(TM). The list price is 
$6995. 


 Remarkably, replacing just one 
400 QIC tape distribution with 
CD-ROMs pays for the Makedisc 
software, software support and 
the complete manufacturing and 
mastering costs for the 400 CD-
ROMs!!!


 


 Young Minds, Inc. was formed 
two years ago specifically to 
meet the needs of the Unix CD-
ROM market, producing the first 
Unix ISO 9660 CD-ROM with 
the introduction of the Free Soft-
ware Foundations GNU and 
MIT's X Window source code on 
disc. Today, products include CD 
Write Once devices for Sun 
workstations and full text index-
ing and retrieval software for 
OPENLOOK, Motif and Sun-
View. Future products being de-
veloped include Multiplatform 
MultiMedia(TM) CD-ROM au-
thoring software for Hypermedia 
application. End users will be 
able to gain access to text, graph-
ics, audio and full motion video 
>from a CD-ROM with software 
only.

ple attended. Everyone intro-
duced themselves to the group.


SUG CDROM project:


Dinah announced the CD-athon 
taking place April 20 and 21 at the 
Dublin Group office building. She 
received approval from the SUG 
board to give free SUG CD's to 
all who participate in the making 
of software for the CD.


Treasurer's report: Checking 
account contains $492.70. We 
will not file a form 990 with the 
IRS this year since we took in less 
than $25,000 this year and they 
did not send us a form (if they had 
sent us a form, we would have had 
to fill it out).


Don't forget to send your dues if 
you haven't paid since Sept. 1990.


Newsletter:


IWL has purchased ads for 3 
months in a row. To insure that 
you will continue to receive a

form and mail it to Lynne Va-
nArsdale, 6528 Sewanee, Hous-
ton, Tx. 77005 (lav@geoquest.-
com). Lynne apologized for not 
updating the US mail address da-
tabase used for newsletter mail-
ings. The email connection to 
Craig Fox who is mailing out the 
newsletters is broken. Hopefully 
the database will be updated by 
the mailing of the May newsletter.


Newsletter:Please send stuff for 
the newsletter.


Focal:Nothing this month.


Speakers: May-Advanced Soft-
ware Automation and Hindsight 
will talk about a C decompiler. 
June-Jim Emmons, GeoQuest 
Systems, Inc. will speak about 
moving to X in the Sun environ-
ment.


If you are interested in becoming 
program coordinator, please talk 
with Dan. We need someone to 
volunteer for next year (starting 
August 1991).


Other Stuff: SUG board: The 
Brookline office is being set up. 
SUG is applying for non-profit 
status. The summer conference 
will be in Atlanta, June 17-19. It 
will be a technical conference 
(read "no exhibits") and the focus 
will be on SPARC.


Speaker:


Pat Shuff talked about NFS accel-
eration and tuning your net-
worked system and network. His 
focus was on how to use what you 
have and make it work better 
without spending money. He fo-
cused on 5 areas: users, system, 
disk, network, and applications.


In considering users, calculate re-
sources and distribute applica-
tions. Get a rough estimate of the 
number of NFS operations being 
performed and what it would take 
to overload the network. Do ev-
erything with shared memory if 
possible. Distribute jobs to ma-
chines best suited to perform the 
particular activity (graphics accel-
erators, database machines, etc.). 
Determine the bottleneck and try 
to offload it.


He reminded us that 4.0 and its 
derivatives need a pmeg patch 
that cures a problem with context 
switching. Running the system 
without the patch causes swap-
ping problems and requires that 
the paging table be recalculated 
more than necessary. SunOS 4.1.1 
fixes the problem.


Disk type also bears on perfor-
mance. IPI disks were designed to 
serve large files and database-
type applications. SCSI disks 
were designed to serve smaller 
files. Try to distribute the number 
of disks on a machine. Synchro-
nous SCSI will be about 4 times 
faster than asynchronous because 
it does not spend a lot of time 
seeking.


Put swap space evenly on all 
disks. (If you have 10 clients and
