If you haven't yet noticed, every 5 minutes on the dot (:00, :05, :10, etc), the Site receives a period of about 5-10 seconds of lag. This is due to the script running to handle pet's health regeneration and a few other things.

At this time, I can't really figure out a way to make it run any smoother.

So, for the time being, I increased the timer to run once every 15 minutes instead of every 5 minutes. I also increased the amounts by 3.

Once the Fall Festival ends, we will be upgrading the software that manages our database. From what I read, it'll be a significant upgrade and should considerably help performance. The upgrade will require downtime though and the possibility of unforeseen issues, so that's why we're waiting until after the festival ends. But hopefully that will help to address a lot of the database issues currently. Time will tell lol.
