Performance Issue with Otrs

[sunil2012]

Hi All,

I am new to OTRS, I am facing the slow issue with my OTRS 3.1.10, It is accessed through the LAN by around 50 agents, I have made changes in the ZZZAuto.pm configuration file for the performance directly. I have added following lines ...
$Self->{'Ticket::SearchIndexModule'} = 'Kernel::System::Ticket::ArticleSearchIndex::StaticDB';
$Self->{'Ticket::IndexModule'} = 'Kernel::System::Ticket::IndexAccelerator::StaticDB';
$Self->{'Ticket::ArchiveSystem'} = '1';

The above settings show me the green signal in the support assessment. I have archived some tickets of 2011 but they were also modified with the change_time and change_by therefore I have updated all tickets for archive_flag column using the sql update statement. But still it is sometimes slow and sometimes works perfect. Please suggest.

Any help would be appreciated for the same. Thanks in advance.

Note -: When it get slow the load average increases in the database server and application server.
Also I am getting the following message in support assessment.....
Check "System Time" vs "Current Timestamp".
There is a material difference (24 seconds) between application server (1357814797) and database server (1357814773) time.
