DEar All<br><br>I have a fairly large implementation of RT running on Apache 2/ MySQL 5.1<br><br>The problem is that it is too slow.<br><br>On looking into the issue, I have realised that if I disable the incoming mails to RT, the speed becomes acceptable.<br>
<br>Once, incoming mail is piped to RT thru rt-mailgate, RT again becomes unbearably slow. I have tried all the things listed in the Performance Tuning section of the RT Wiki.<br><br>I believe at the time of writing into the database, mails take a huge amount of time.<br>
<br>Is there a solution to this, because otherwise I might have to uninstall RT as the customer is not very happy about the performance. <br><br>The expected load is about 50,000 mails(tickets-created or corresponded) per day and about 10 helpdesk agents to handle those tickets in 3 shifts of 8 hrs each. Hardware is dual core Xeon with 4 GB of RAM. Database size is currently around 4 GB.<br>
<br>Mostly, I feel that the problem is with the Attachments table as queries onto this table take a very very long time.<br><br>Any help would be deeply appreciated,<br><br>Regards<br><br>vbg<br>
