There are only few Benchmark tools for OS4 out, i found cgxbenchmark and scsi-speed.
My experience is that OS4 is lot faster in Intuiton, graphics are parly slower or faster as OS3,
drive is slower, memory is slower.

Then there is a native Scsispeed Version for OS4, but not a actual for OS3. ScsiSpeed is not very accurate.
But i make a 68k Version of the Source that comes with the OS4 Version:

If you have a slower Harddrive the difference is lower, if you have a faster the opposite.
Test was made with a 36 GB IBM SCSI Harddrive. The Values are RawSpeed only,
without Filesystem.
If you access 2 Drives with OS4 at the same time, for example for Burning the
performance drops. Thats because of the OS4 cybppc.device, it has not a True DMA.



Than i make Benchmarks with Sysspeed. There exist only a 68k Version, such speedtests should only made
with native Versions. But a) the exist tools test only very few Functions b) its a good way to find out whats
the speed of the Emulation because a lot of Applications and Games not available native.

Red is OS3.9 CPPC 68060 60 MHZ, 70ns, CVision 800x600
Green is OS3.9 BPPC 68060 60 MHZ, 60ns, BVision 640x512
Blue is OS4 CPPC 604e 233 MHZ, 60ns, CVision 800x600
