Slow loading of pages when lots of games are installed
 

Not sure if anyone else has this problem, but my site has a ton of games in the arcade, which since adding them, is causing a slight problem

When you goto the arcade link, the page doesn't appear for about 10 seconds, sometimes longer
During that time, the cpu usage on the server goes upto 99% (Mysql process it seems)

Don't suppose there's any pending update to account for larger game library's is there?

You should just reduce the Amount of Games per Page:
AdminCP -> Arcade Main Settings -> "Amount of games to show per page"

Think about using Categories ... ;)
