Chat plugin is slowing my website BIG TIME

Hello!

So i have installed the chat plugin(one of the main reasons of why i made a membership with wpmu).

But once he is installed my website became really slow.
Im getting 4-5 SECONDS OF DELAY JUST BECAUSE CHAT PLUGIN!!(according to pingdom test)
Please help me to fix it a.s.a.p, as i can not run my website without the chat plugin enabled.

Thanks , :slight_smile:
