In short terms: it isn’t slow 🙂
Compared to an native application it is slightly slower but there should be not that much difference. (This is true at least since version 0.42 of JWildfire at which I have tried to optimize the hell out of it ;-)) For the maximum performance you should use Java 7.
I have created some flames for benchmarking. I used Apophysis7X15 as reference because it is very popular. Below are the results (the used *.flame files are linked inside the table):
