My Vps Hang from the time I reach the average 30K visits a day i'm starting to doubt if its k2 or overall Joomla :( the only component installed is k2 and i'm using it for blogging. If anyone here use k2 on a high traffic site please give me an advise. thank you.

 

PS.

 

I already enable cache from global config & system plugin

 

 

I'm just a newbie. Please help.
