Just wondering..

Perhaps this problem is related to BPPC PPC CPU model always running slower (reason unknown, only QEMU config difference is CPU model) than CSPPC PPC CPU model.

If you switch to BPPC config and use 2.2 DLL, do you get same slow speed and crashes when using CSPPC and new DLL? (or use CSPPC config but force CPU model to BPPC using manual config entry ppc_model=603ev)

Also testing with some much newer (but compatible) PPC CPU variant may show some differences. Not sure which model yet.. It is quite possible that QEMU developers don't use or test very old PPC CPU models.
