You could try the expat one, this was one of my reasons for using expat
as expat was still faster, despite the prohibitive event chaining
overhead. It's an interesting architecture, but performance is ****.

Did you look at memory consumption as well? That's also a biggie with
Eiffel. If you don't use memory, like the C versions do, performance is
much better.

If you need performance, absolutely. As we can now use agents, we
probably can cleanup this a bit, and have the event infrastructure sit
on top of that.

BTW, I've always found the ISE profiler an indispensable tool in solving
performance problems, but as you say, it'll be a lot of work.
