GCC 4.1

Hi

I'm seeing significant improvements when compiling a VM with GCC 4.1
over the stock Unix VMs. They are almost too good to be true.

stock 3.9-9 vm, GCC 4.0.3:
56437389 bytecodes/sec; 2609047 sends/sec

compiled with GCC 4.1.1:
113676731 bytecodes/sec; 4011617 sends/sec

That is about twice as many bytecodes/sec and about 50% more
sends/sec. Can that be?

Cheers
Philippe

Don't know, but could you tell me, how you did test that?
(and which hardware configuration?)
