When will be updated this plugin

I’m guessing it will be updated when it needs an update. (Properly written plugins don’t tend to just need random updates for the sake of updates.)

AS Jason says, I don’t think there is a need.. APC for me during my tests, is still the fastest method I’ve found to a quick loading website. I’ve outlined my whole configuration here, https://boi-infinity.com/wordpress-optimization-2014-behind-boi-infintity/

Thanks works fine
