I turned on the profiler, and i got the following results for my page:

The whole-request is between 16100 and 19500.
Only one stage is taking the most time:
org.apache.cocoon.processor.xsp.XSPProcessor-1
this is between 15900 and 17800.
I reloaded the page four times, and I got the above results.

All pages are almost the same, only with different query-s. 
And it does not get faster after a few reloads.

Intel Pentium III (Coppermine) 566MHz
128MB PC133 RAM
15GB HDD

Linux Redhat 7.0 with kernel 2.2.16-22
Apache 1.3.12-25
Apache JServ 1.1.2-1
Java (TM) 2 Standard Edition Version 1.3.0 for Linux
Cocoon 1.8
mm.mysql 2.0.1 jdbc driver
Netscape 4.75
KDE 1.1.2

And yes, there is at least 30 secs of permanent disk activity, but only
on the first reload of the page after changes.
