I do have the same problem: ever since my site migrated over to K2, it has become sluggish. When I edit an item and save it, it takes 17 seconds, sometimes even longer. I have had it time out due to the php limit. The contrast is stark, as before It was really fast and we are not talking about a huge site that I run, I have maybe 100 items and 95% of them text. I am just concerned, as I am one person and if it is already this slow with me, what will happen when more users are online? I'm using 2 levels of categories and all categories inherit the settings from the upper category and I noticed when I set that, it was timing out regularly, for some reason it is doing massive work in the background like this. Is there a document or FAQ for performance tuning? And kind of settings that should be increased to give K2 more breathing room?
