As it is perceived currently: the compiled code does not perform better on PowerPC 970 (aka G5) than on the older processors.
PPC 970 requires special optimization strategies which are not resolved in the current JIT compiler.
Possible areas for improvement:
-
set up the branch hinting properly, so the branch can be predicted more accurately
-
make use of multiple cores
-
revise the emitted code in respect for the multiple execution units and make use of out-of-order parallel execution as much as possible
-
revise the usage of various PPC instructions, if there was a better choice for PPC970 which is faster
