Hey, this is cool. What surprised me was the number of time compiling
.class files beat out compiling .java files. I wonder why that
happens...
I suppose "gcj -O2" is a reasonable guess at picking right compiler
options, although "-O3" is supposed to be the general `maximum
optimization' flag. I'd love to see results with different options used
(-O3, different alignment options, basic block reordering, -mcpu=***,
etc).
Thanks for making this work available!
