So I have been trying to figure this one out. So I setup a new Xenforo site. One is on regular shared hosting and one is one semi dedicated hosting. Now of course the semi-dedicated is going to be alot better. But is there anything I can do about this high I/O usage on the shared hosting? I have tried everything even setup a file cache like on my main site and it's still happening. Contacted host and they didn't see a problem with it, but to me it just doesn't seem normal. Is there anything that I can check? Any ideas? New site. (shared hosting) My other site on a (semi-dedicated) just for comparison.
