I have been a SCO UNIX user, never an administrator...so I am stumbling around looking for information.
I don't know too much about what is onboard in terms of hardware, however; I will try my best.
We have SCO 5.07 and have applied MP5.
We have a quad core processor with 4 250 GB harddrives.
Yesterday, we had discovered that we were not using SMB (SCO Multi-Processing), so I had applied that.
I am finding though that when someone is running something, it is terribly slow.
I know that I will have to provide more information, but I just don't know where to start.
Does anyone have any suggestions?
I have a bunch of frustrated users.
Thanks
If you have sar enabled then sar(1) can give you useful historical performance data, if I/O appears to be the problem then iostat(1) will give you a picture of I/O performance now. vmstat(1) will give you system performance information now, I like top(1) that shows a process list with the largest resource consumers at the top and mpstat(1) which is multi-processor aware and shows the amount of CPU being wasted by I/O waiting (i.e. memory and disk access).
Take a look at: http://aplawrence.com/SCOFAQ/FAQ_slow.html , UNIX Performance Management and Unix / Linux / BSD Cheat Sheets II for starters.
Which of these commands are available in SCO Unix I am not aware so you will have to give them a go to find out!
P.S. Tis looks interesting: http://williambader.com/museum/dell/scotuning.html
