We were running Horde 2 / IMP 3 on AMD 64 bit dual processor (Opteron) system.
We were finding the performance/speed is excellent.
We are currently running RHEL 3.0 Update 5 AS on that system.
After migrating to Horde 3/IMP 4 and other applications, CPU consumption goes
even up 95% at peak hours and the response to the users is poor during that
We tried performance tuning of HTTPD, PGSQL, CYRUS-IMAP etc... but the poor
response time continues during that peak hours.
Can anybody comment on performance/response time improvement if upgraded to
Kernel Ver 2.6 (ie. RHEL 4 )? We are planning to upgrade to RHEL 4. If any of
you has any feedback on that, please share with me.
