If you want you can see if this makes any difference in performance, I made these changes for a server. Though your issues with gravity (not speed) are because this plugin changes your gravity to act as a parachute. I suppose your gravity value could be stored when you spawn to be used as your normal gravity to reset to. For the time being change weapons and see if that helps, I know it will for speed but I don't recall if gravity is also effected when doing so.
