- I am running a DECstation 5000/200 as a server and all we did was to set the
- buffcache to about 50% to set aside a bunch more memory for file caching.
- We run dataless configuration with /usr being exported to the clients and
- / root and swap on each workstaton. The one thing I would suggest to really
- speed up writes is to add a prestoserve board. I have one on my 5900 and
- it really makes it zip. I can actually feel the difference when I turn it off.
-
- Probably the most important thing is to disable logins to the server. I
- made the
- mistake of letting one person compile on the server and all hell broke
- loose.
- Next thing I knew is that we were getting nfs timeouts and everyone
- started
- logging into the server to work (because of all the timeouts). Don't
- let that
- happen to you.
