We have a pretty high load mail server that does AV and spam filtering. I am looking to perf. tune this machine. It's FreeBSD 4.9-REL and Postfix. I am trying to correlate the info in systat to things I need to worry about. I am using systat with vmstat output since that seems to basically show everything you need to see. By the way, I did read 'man tuning'.
First, I see that my memory is fine: 3 users Load 9.75 4.46 3.24 Mar 15 17:02 Mem:KB REAL VIRTUAL VN PAGER SWAP PAGER Tot Share Tot Share Free in out in out Act 106712 8704 3036376 30772 35356 count All 502468 37816 3878800 181488 pages The major thing I'm looking at is SWAP PAGER: SWAP PAGER in out I see that I have processes in the run state and 14 waiting on the disk: Proc:r p d s w Csw Trp Sys Int Sof Flt 8 14 77 6305 297429015 950 1863 2293 I have 77 processes sleeping. I have 0 processes in w state, which means that my CPU isn't having a problem. I am spending a lot of time in sys and the rest in user: 49.5%Sys 1.7%Intr 44.5%User 0.0%Nice 4.4%Idl Here are my disks: Disks aacd0 acd0 KB/t 13.19 0.00 tps 111 0 MB/s 1.43 0.00 % busy 2 0 >From %Sys I would say that disk is a problem for us. However, I'm having problems really understanding the numbers for Disks. We are running the server on RAID-1 (2 disks) IDE. What should I be looking for here?
