I get 24MB/s each according to hdparm -t on my hdd's and both are on the same channel. This is much better than i ever got with 2.4 even when only one drive was on a channel. Right now my k7-2 750 is at 849mhz with a FSB of 114Mhz and PCI at 34Mhz. my nbench performance under 2.2 is comparable to results for 1Ghz t-bird's so i'm happy with 2.2. The only thing that would make me want to upgrade would be latency patches. I'm convinced 2.4 has performance issues so i guess i'll be using 2.2 until 2.5 begins. Is it really only 1 or 2 people having this Via corruption problem? i doubt it's a bios problem because wouldn't 2.2 be effected by a bios bug if 2.4 is? In either case the changelogs dont show any fixes for it. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org Please read the FAQ at http://www.tux.org/lkml/
