Performance investigation, very high runq-sz %runocc
I've just been handed a hot potato from a colleague who left ... our client has been complaining about slow performance on one of our servers.
I'm not very experienced in investigating performance issues so I hoping someone will be so kind to provide some guidance
So I just can't figure out where these huge runq's are coming from... can someone please tell me what I'm missing or what would be the next thing to check?
Maybe it's staring me right in the face but I just don't see it
Many thanks in advance!!

Achenle, here are the outputs of "prstat -a", "vmstat 2 20" & "iostat -sndxz 2 20".
And yep I think the 'solution' to this performance issues before was the "throw as much CPU against it and hope if that resolves it"-approach.. . Which clearly didn't have the hoped for effect.

When compiling I get the following error: (the error is at the end, the other errors in between are because I've ran the script several times so... (0 Replies)
hello everyone ,
Im new to HPL. i wanted to know whether High performance linpack solves linear
system of equations for single precision airthmatic on LINUX.
it works for double precision , so is there any HPL version which is for single precision.\
thanks . (0 Replies)
Sorry, I am not really from a computer science background. But from the subject of it, does it mean something like multi processor programming? distributed computing? like using erlang? Sound like it, which excite me. I just had a 3 day crash course in erlang and "Cocurrency oriented programming"... (7 Replies)
I am interested in setting up some High Performance Computing clusters and would like to get people's views and experiences on this.
I have 2 requirements:
1. Compute clusters to do fast cpu intensive computations
2. Storage clusters of parallel and extendable filesystems spread across many... (6 Replies)
Hi folks,

Hello everybody.
I have a problem with my AIX 5.3. Recently my unix shows a high cpu utilization with sar or topas.
I need to find what I have to do to solve this problem, in fact, I don't know what is my problem.
I had the same problem with another AIX 5.3 running the same... (2 Replies)
