i can only run about 3 bots right now and it will use about 80 percent cpu. 3 works perfectly but as soon as i open a 4th it lags like hell. i know it shouldnt be like this because i used to run 5 eoc bots with little lag and this is an outdated game.

I think more RAM might help

idk your lucky you can run 3 , i lag with 2

I am currently running 3 clients with 3 bots on each client :P

The CPU usage of OSBOT is INSANE, it is not a problem with your ram. I can run around 12 Advertising other bots isn't allowed. clients at 80% CPU and I am at 90% CPU with 3 OSBots, only downside that I can find of this bot

I'm getting so mad with people who just say "get more RAM". Chances are, that isn't what's causing the problem. For most computers, the bottleneck (what's slowing it down) is the CPU which is more difficult to upgrade. Apart from closing opened programs and run it in low CPU mode there isn't much you can do. Open up task manager and compare how full CPU usage is and how full RAM usage is.

Tried virtualbox yet?
