I haven't tried the Win 95 JDK stuff, but its interesting to note that
the Hotjava browser is entirely Java code, and it certainly works
acceptibly quickly. Admittedly that's on a (multiuser) SS10, but its
even mostly OK on my SS1...
I certainly don't think the current Java technology is the limit in
speed. With minor tuning to the compiler you could get ~2 time speed
improvement. With better runtimes there'll be a 10-100 times improvement.
So, for the moment at least, Java is certainly fast enough for user
interfaces, but I wouldn't start solving CFD problems with it.
