Hello!

I have a weird problem with a server. I use deadline.
The output of vmstat is:

It seems strange because iowait is at 90% but nothing is trasnfered to/from disk. Why is that?

I run postgresql on this server and I'm not satistied by it's speed.

Single Pentium IV, IDE disk.

What can be the problem?

Thank you very much!
