concrete5 slow performance
Permalink
Our CMS running an old version of concrete5 version 5.4.2.2 on red hat linux with php 5.1.6.
The CMS has been running fine for the past two years with no problems until last week.
The page loads tends to double when users are logged into the CMS and make changes. The database is quite large and apache seems to be using up a lot of processing power. I have followed the usual steps mentioned in other forum topics. We have Zend optimiser running. Caching is turned off.
The performance improves when users log out of the CMS. Performance drops when we more users making changes to the site via the CMS.
I was wondering if anyone had tips on what we need to do in order to understand what the underlying problem is. Are there any databases tables we can truncate. I know we can update apache and the concrete5 to the latest version but before I do that I wanted to know whats the best way to diagnose what services the CMS is struggling with.
Thanks,
