I'm not sure about the 60% (if it's more or less), but I can tell you that I am
seing the same thing here. The only exception seems to be these small benchmarks
(notably the Sieve one that comes with TYA) - JDK 1.2 is faster there. But in
all "real world" tests I've made, JDK 1.2 has been about as fast, or, usually,
significantly slower than JDK 1.1.7.
