Hello, I have three websites on a VPS server. All three websites have same admincp settings (performance). One functions fine; posting - opening threads, like and the other overlay features works perfectly and very fast. But the other two forums... Posting, opening threads, liking something is painfully slow. I tried many things; currrently the cache functions are in place: Code: $config['cache']['enabled'] = true; $config['cache']['frontend'] = 'Core'; $config['cache']['frontendOptions']['cache_id_prefix'] = 'xf_'; $config['cache']['backend'] = 'File'; eaccelerator is also installed on the server. My attempt to diagnose by disabling and enabling the addons was unsuccessfull. Although all addons were disabled, posting, liking etc. was extremely slow and results sometimes in timout errors. The server specs: CentOS 5.7 php 5.3.10, suoshin, eaccelerator, mysql 5.5 (newly upgrated but I have had this problem when I was running 5.1 too). How can I find out what this is caused by?
