| |
This is 2.6.0-test2 on a Celeron 900:
raid5: measuring checksumming speed 8regs : 1640.000 MB/sec 8regs_prefetch: 1316.000 MB/sec 32regs : 824.000 MB/sec 32regs_prefetch: 788.000 MB/sec pIII_sse : 1744.000 MB/sec pII_mmx : 2244.000 MB/sec p5_mmx : 2400.000 MB/sec raid5: using function: pIII_sse (1744.000 MB/sec)
Why doesn't it select p5_mmx if it is 37% faster than pIII_sse?
