| |
Hello, world!\n
I've tested RAID-5 on my new dual athlon box, and got the following messages during system boot:
raid5: measuring checksumming speed 8regs : 2550.400 MB/sec 32regs : 1702.000 MB/sec pIII_sse : 4735.600 MB/sec pII_mmx : 3910.800 MB/sec p5_mmx : 5016.800 MB/sec raid5: using function: pIII_sse (4735.600 MB/sec)
Why does the kernel decide to use the pIII_sse function, even though the p5_mmx is faster?
The kernel is 2.4.20-pre5-ac1.
