Just wanted to note, if you are referring to my clericBot being bloated, you are right it is somewhat.
I'm going to be writing a premium version soon, but in the meantime if you are using my clericBot and want to make healing as fast as possible, just disable the other stuff.
In [General] set DebuffAtStart=FALSE, and anything else you don't need it doing set it to FALSE as well. You will want HealAtStart=TRUE and HealCheckTimer=0s. Also if you have any Group Buffs set make sure none are set to GroupBuffCombatN=TRUE, if you have any combat buffs it will spend time checking peoples buffs in combat.
The healing routine in that clericBot itself is still not the most efficient routine, but I can't see it delaying by more than a few tenths of a second on a heal. I don't really play in the high end game anymore, haven't even ran a group with a cleric in UF so if a few tenths of a second is to slow then yes my free clericBot is going to be inefficient at the job. The premium version I release in the next week or two should have about 3x the reaction speed of the current free clericBot.
