SATA-performance with AHCI

2006-12-04 Thread Martin A. Fink
Dear all, now I was able to do a performance test with an Intel ICH6R chipset. Basic hardware data: - Intel Pentium 4 Xeon at 3.2 GHz - Intel ICH6R chipset, AHCI enabled - Intel Hyperthreading On and Off - 1 GB SDDR RAM - SATA controller onboard (4x) - SATA harddisks 250 GB I used SuSE Linux
