Apache HIGH CPU usage!

[szafar]

Hi Guys,

i came across a new problem, we have some users with huge emails data ( 4-5 are under 5 GB each, and 2 are with more than 10 GB). we are using HMAILSERVER on backend. When we add their IMAP accounts into TINE20 (Milan), its respond time increase a lo with HIGH CPU usage up to 100% all time. after seeing all this, we configure 'memcached' but its not seems to help alot. CPU usage decreased a bit but still in 90%. i have seen alot of thing, and lot of thing but nothing working for me.

here is the setup file:

<?php
return array (
'setupuser' =>
array (
'username' => 'admin',
'password' => '011222222222222222222222222',
),
'database' =>
array (
'adapter' => 'pdo_mysql',
'host' => '192.168.1.42',
'port' => 3306,
'dbname' => 'xxxx',
'username' => 'xxxx',
'password' => 'xxxx',
'tableprefix' => 'xxxx_',
),
'logger' =>
array (
'active' => false,
'filename' => 'C:\\WINDOWS\\TEMP\\tine20.log',
'priority' => 5,
),
'caching' =>
array (
'active' => true,
'path' => 'C:\\WINDOWS\\TEMP',
'lifetime' => 3600,
),
'tmpdir' => 'C:\\WINDOWS\\TEMP',
'session' =>
array (
'lifetime' => 86400,
'backend' => 'File',
'path' => 'C:\\WINDOWS\\TEMP\\tine20_sessions',
'host' => 'localhost',
'port' => 6379,
),
'filesdir' => 'C:\\WINDOWS\\TEMP',
'mapPanel' => false,
'profiler' => 'true',
'queryProfiles' => true,
'cronuserid' => '7ad41bc0c70ed0dae590a3147f5dba5431eb21f1',
'sessionIpValidation' => FALSE,
'caching' =>
array (
'active' => true,
'backend' => 'Memcached',
'host' => '127.0.0.1',
'port' => 11211,
),
'pdfexport' => array(
'fontpath' => '/var/www/tine20/test/unifont.ttf',
'fontpathbold' => '/var/www/tine20/test/unifont.ttf',
'fontembed' => true
),
'actionqueue' =>
array (
'adapter' => 'Db',
'driverOptions' =>
array (
'host' => '192.168.1.44',
'dbname' => 'xxxx',
'username' => 'xxxx',
'password' => 'xxxx',
'type' => 'pdo_mysql',
),
),
);


i need to fix this thing quickly,
any help?

Thanks

the email message cache needs to be filled. but only the headers are cached. during the cache update, cpu usage could go up, but > 90% is a lot. perhaps you need to run this overnight? should not take longer than a few ours to fill the cache and afterwards it should be OK.
