Priest party bot freezing issue

[Odd]

I had configured a priest bot that would support a group of my friends and so far it is working great except one thing: the bot often freezes(returns to normal after several seconds) when we deal mass AoE damage to mobs. I think perhaps the bot is being fed too much information at the same time so I tried to utilize the verbose and squelchDomain functions to reduce the amount of spam being written on the console. It did seem to have helped a bit but it was not a significant change and still frequently lags. Relogging completely or typing "relog" does alleviate the freezing but it returns as soon as we AoE more mobs.

Is there any other way I can reduce the lag on openkore?

My computer specs should be fine but I'll post it anyway:
