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:
$config['cache']['enabled'] = true; $config['cache']['frontend'] = 'Core'; $config['cache']['frontendOptions']['cache_id_prefix'] = 'xf_'; $config['cache']['backend'] = 'File';
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?
