The -hotspot compiler (also -client and -server) require kernel threads. If you want kernel threads, you have to pick an operating system other than FreeBSD. >It seems to be a lot >faster than -classic (until it crashes that is). Or is it just me >perception? It depends on your application. For sustained execution, -server is about 25x faster than -classic. Also, -server is about 5x faster than OpenJIT (which is about the best you can do under FreeBSD).
