OK the very first thing I looked at was something called "execsnoop" which monitors system calls. One single click (in this case, clicking on CRGWeb from an authenticated wiki session , but I get something similar for any click). IMHO this is a very silly number of system calls for a single click.  It calls rlog on all 90-odd files in /webvols/wiki/twiki/data/CRG ! For the Unix web it does it on all 203 files!

I can see why it is slowing down.
