Thanks for your help.

I did tried it on my test server and it seems to be a bit faster,
but that could be due to caching. Strace still didn't show any access
to the cyrus.squat file.

For information: We only use squatter. No Xapia. And we had much faster
search with Cyrus-Imapd 2.3.x and 2.4.x. I don't have the timings form
the old system but our users are complaining and they receive timeouts
in our horde/imp webmailer, which they did't receive before.

Any other ideas are appreciated.
