Reducing lag in my particle script

[Nemesis6]

My particle script - Check Scripting: Beta Testing

How can I reduce lag in this script? Make the delay longer, but that can't be done with the fire, it's just perfect now. And advice?

I'd really like to know if there's some miracle that can make my script unlaggy...

In advance, thanks.

Increase the delay and reduce the amount of Drop effects.
