how fast can gcc with java be, compared with a jit


I am just wondering how fast gcc can get ?
Which optimizations are thought to be included there ?
please see what ibm have come up with...
Maybe running java-code fast needs these optimizations at least.
They seem to be specific for java-code, and not for c-code (which gcc was
made for).

When doing FIR-filters i have found that ibm:s jdk1.3 is 20 percent faster
than
gcc-optimized c-code !
