Hello, it is c# or xml fightclass?
To get faster reactions you need to "unlock FPS limit" (in advanced general settings, you can also try to activate option "Improve combat rotation speed (this option can skip spells)"), if you use XML fightclass put bigger FPS (in your fightclass settings) (or remove sleep time in c# fightclass).
What is slow is to use LUA (or WRobot functions that inject code), try to avoid if you can, for lua if you cannot remove it try to combine scripts. You can use debug option (in xml fightclass) to found slow spells.
