Basically, I've just installed XF but I'm having big problems with the speed, overall the site is noticeably slower (and I hate to compare, but a lot slower than say phpBB). However, my main concern is timeouts when I make a change to the configuration or a template. It will timeout say half way through it's Purging Cache Data (or whatever) process and at one point it left me with a broken template.
Is there a way to correct this? People are saying it's time for a new host, but I use StableHost (who are supposed to be one of the best), and I never had any speed or timeout issues at all.
I have read, that turning on caching may assist? Is this true? Are there any drawbacks? I will have a dynamic portal installed with regular news feeds, will caching slow down the updates of my feeds onto the portal page? (XenPorta)
