[opencms-dev] OpenCMS performance tuning

Hello,

I have started to notice a particular pattern to our problem. On restarting the tomcat, the application is typically slow until I have clicked all the relevant pages to create a cache.. Once this happens the response time is very good BUT a few hours later, the application slows down totally which I fear is because of the cache expiration.

Is this a flexcache configuration? And if so, where can I change it to not expire?? And is there any consequences to this action?

Many thanks,
sg
