Hi, all.

We have played with Horde 3.3.6 for mailing purposes only (with postfix) for
a while and all looked fine with a few users.

When we released it for production (about 200 users) CPU consumption went up
to 100% mostly due to httpd processes.

Output from apachetop shows high number of requests/sec of two scripts
(login.php & index.php):

We read the Admin FAQs but nothing helped. Has someone had a similar
experience?
Any hints about troubleshooting this issue?


Thank you for your support.
