The difference could also be attributable to the longer branch misprediction
penalties of the Pentium II compared to the newer PowerPC chips.
The x86 instruction set is harder to decode and takes more cycles
to do so, so a mispredicted branch takes more cycles.
Meanwhile, the PowerPC processors have about the lowest branch
misprediction penalty of any chip I am familiar with.
The bytecode branch, at least, will likely be mispredicted.
