Lol, yes, I did that a lot. I haven't done that for a while (last few times was when I optimized the Jasper 2 runtime), but I'll probably start over again to make sure there are no regressions. I don't know any other way to improve performance ;-) BTW, this is off-topic, but I have an OptimizeIt question: how do you run it with Hotspot (on Windows) ? Everytime I tried, it crashed and/or the profiling didn't work. So I've been using it with the classic VM, but this obviously can change the results. Any trick you might know to make Hotspot work ? > We are way beyond the point where 'intuition' was the > primary factor. > > If you believe o.a.c.c can be optimized - feel free > to prove it.

Even if you manage to edge Coyote HTTP/1.1 performance, it's not going to be by a wide margin. Having written it for a simpler API would also probably make the Coyote HTTP/1.1 implementation cleaner and more maintainable. BTW, Strings are bad but needed IMO for security, right ?
