Performance when init particle

[rainstormza]

I tried to measure performance with this demo (https://rpj.bembi.org/).
When the first load it's going to stuck for a while and then it will paint the dom (fps down to 8-10).

This lib has the same behavior.

Is there anyway to improve this?

A huge refactor is being written right now, so I'll check the performances on next version.
However I suppose it won't be easy to improve first load.
