Slow response on IMP

[imp@gurubase.com]

Hi all,

Our IMP seems to response slowly.

We suspected that it may be related to the horde session.  Could anyone
help?

We encounter four situation when the response is slow and we find that
at that moment the CPU utlization is very high for the PostgreSQL process.

1. when loading the index.php3.
2. after pressing "log in" button.
3. after pressing "compose" button.
4. after pressing "logout" button.

Other than this, sometimes there is a problem that the left hand menu
bar fails to refresh after logging in or logging out.

Software Config.
================
RedHat Linux 7.0 (Kernel 2.2.16)
Horde 1.2.4
Imp 2.2.4
phplib
PostgresSQL 7.0.2

Regards.
