Eek, this was bumped quite a bit. Not even sure if the OP will look at this, but are you using the latest revision?
If not, I would, because there’s been a lot of optimizations recently.
Second thing, experimenting with DarkRP for a while, you can go lower than 33 tick, and be fine. (Wouldn’t go lower than 20 or so.)
Third, wouldn’t use Durgz Mod, or however you spell that shit, has 5 - 6 Think hooks that run player.GetAll(), which will cripple a server, when it starts getting populated.
Fourth, wouldn’t really use a Think hook for anything, if there’s a much better solution for it.
Hope this helps whoever’s trying to increase the performance, if the OP has completely forgotten about this thread, seeing as how it’s about a week old.
