| |
Hello,
It seems that there is something wrong with measuring checksumming speed - on my two P3 boxes linux chooses pIII_sse but pII_mmx and p5_mmx are reported as faster instructions:
2.4.10-ac10/Pentium3 733: raid5: measuring checksumming speed 8regs : 1266.400 MB/sec 32regs : 898.400 MB/sec pIII_sse : 1508.000 MB/sec pII_mmx : 1643.600 MB/sec p5_mmx : 1730.400 MB/sec raid5: using function: pIII_sse (1508.000 MB/sec)
Podobnie na drugim systemie: 2.4.10-ac10/Pentium3 933: raid5: measuring checksumming speed 8regs : 1603.600 MB/sec 32regs : 1138.000 MB/sec pIII_sse : 1910.000 MB/sec pII_mmx : 2081.600 MB/sec p5_mmx : 2189.600 MB/sec raid5: using function: pIII_sse (1910.000 MB/sec)
Best regards,
Krzysztof Oledzki
