are you running any database in the same server?. if possible try to stop unwanted processes eg. sendmail etc.
what is you disks setup ?

I strongly suspect that the issue is with the software (Java/VB etc) since I have been in exactly the same situation. Users and programmers were complaining at the speed of my database and server because their VB statements were taking 2 minutes to get info out of the database - however they neglected to point out that 1:59 of this was executing java middleware on a PC inbeteen the VB and the database.
Take a look at the logfile timings of statements of all software before admitting that the problem is with the server.

However one last thing you should test is the settings of the network cards.
Do a lanscan then lanadmin -x [ppa] on the interface, then compare it with the settings on the switch/router. They must be the same duplex value or you will get terrible network performance.

I agree with Steve. One other thing I always check is my /etc/resolv.conf If you are having networking problems reaching your DNS server(s), you can get a lot of weird performance problems as well. Try pinging your DNS servers to see if connectivity with them is up.

Hi,

I have attached the swapinfo -m and vmstat,
and we are not running sendmail. The server is only used as web server.And its clustered and running only one package(to up the iPlanet and chilisoft daemon)

TIA
