Kernel is 2.6.11, ata_piix version 1.03 streaming write with bs=1024k: ~50 MB/sec So this probably a SuSE issue !?!? I should switch to debian :D sorry for the noise. regards roland --- Weitergeleitete Nachricht / Forwarded Message --- Date: Thu, 21 Apr 2005 21:04:09 +0200 (MEST) From: for_spam@gmx.de To: linux-ide@vger.kernel.org Subject: ICH6 / SATA performance problems Hello, i have a strange sata performance problem with my new system: MoBo: Gigabyte GA-8I915G-MF Chipset: Intel i915G (Intel ICH6 Southbridge) OS is SuSE 9.3 Professional with Kernel 2.6.11.4-20a-smp (with HT) or 2.6.11.4-20a-default (without HT) - I installed and tried both (switched off HT in Bios and installed default kernel) Initially, performance seemed quite ok, but as i did some of my usual tests (dd if=/dev/zero of=test.dat bs=1024k count=8192) i wondered about the bad performance values. For writing i get just below 7 MB/sec !!! ata_piix on SuSE 9.3 (2.6.11.4-20a) is version 1.03 For comparison, I booted my knoppix 3.7, Kernel 2.6.9 and surprisingly I get 43 MB/sec - that`s ~6 times faster and a value i would have expected. ata_piix on Knoppix 3.7 (2.6.9) is version 1.02 Any hints what`s going wrong here and how to fix this issue ? thanks in advance roland P.S.: please put me on CC because i`m not on this list. -- +++ NEU: GMX DSL_Flatrate!
