We've been using SunOS 4.0 on a network of 40+ diskless 3/60s, and 40+ disked sun3s and sun4s of all types (3/60, 3/75, 4/110, 4/260) all served by 4 4/280s serving 600 users for over 6 months in a CS instructional/research setting. We have Sun supplied products only (yup, that means 451's on the 4/280s). This includes sendmail.mx, named, 4 subnets, mixed vendor network (IBM RT, DEC MVAXen II's and III'3, Stellar, HP 800, Mac II, Encore Annex, Imagen, DEC Delni). EVERYTHING WORKS JUST DANDY :-) Bent [[ Yeah, but, are any of your machines confined to 4 megabytes? And the Imagen stuff really works? You're using Imagen's Unix host software? Because I found a big bug in their stuff that 4.0 tickled on a regular basis. Perhaps you have a newer version. --wnl ]]

A common theme seems to be "well, if you take sun's suggestions and
fine-tune the kernel, don't run any daemons you don't have to (especially
rwhod), take the second hand off your clock, make your perfmeters use 5
second update intervals, etc, you can get 4.0.1 to run almost as well as
3.4 on a 4-Meg 3/50". What I wonder, however, is if all these comparisons
are to a vanilla 3.4 system, or to a similarly fine-tuned 3.4 system.
Another question: does SunOS-3.6 exist? I've seen various references to
it (especially wrt Van Jacobson's new TCP code), but as far as I know,
3.5.2 is the latest and greatest from sun (not counting 4.X, which may be
the latest, but clearly isn't the greatest).
