The raid5 code in 2.4.17 seems to select the slowest available checksumming function.
Part of dmesg output follows:
[...] raid5: measuring checksumming speed 8regs : 2148.000 MB/sec 32regs : 1900.400 MB/sec pIII_sse : 1272.000 MB/sec pII_mmx : 3291.200 MB/sec p5_mmx : 4212.400 MB/sec raid5: using function: pIII_sse (1272.000 MB/sec) [...]
The machine is an Athlon XP 1400MHz on an MSI K7T266Pro2 board with 512 Mb of PC2100 DDR.
