Sorry I wasen't specific about system type when I asked for tuning tools. I am running Sys5 on a Dual 83/20 (which I use for software work -- single user normally). The disk subsystem is the prob bottleneck. I fired up about 30 small compute bound processes and system response was still reasonible (No swapping... I have 3/4 meg of user area -- plenty for what I am working on).. As soon as I kick in a few processes that go for the disk, response time goes thru the roof. I would like to know if there are any good internals books for Un*x which give system variables to watch for. Something like # of physical disk I/O's vs amount of cache hits and maybe disk wait time. That sort of thing. I've done tuning on a few other systems but it seems that some of Un*x tuning remains somewhat a mystic experence. Don't get me wrong I still would rather work in the Un*x environment then some of the others I worked with. Again, thanx to the people who gave me some pointers and here is the specific info they suggested I give to help them give me better info.
