I have installed 9.1 on my new HP P4 and did not notice any performance issues there. Finally this last weekend I installed 9.1 (clean install) on my home server and found it to be painfully slow. This server is an HP with Pentium 200 MHz and 128 MB RAM. SuSE 9.0 ran fairly well on this PC but I wanted to try 9.1 because I had seen reports that the new 2.6 kernel gave better performance. Instead of being better, 9.1 was much worse than 9.0. In searching the archive for this topic, I found several posts on this subject. I read one suggestion to look at hdparm to see if DMA is enabled. DMA is enabled and the numbers I got were similar to what I got on another PC that I have with 9.0. The server PC with 9.1 is using RAID-1 while the other PC is not RAID. Could this be a RAID issue? Does anyone have any idea why 9.1 is going so slow? Are there any other things I can check besides the output of hdparm? Using dmesg I looked at the boot messages md: personality 3 is not loaded! md :do_md_run() returned -22 md: md1 stopped. This looked a little suspicious to me although I am not sure if this is a problem or not. I did a google search on do_md_run and found some discussions about a problem with an earlier 2.6 kernel but I am not sure what to make of this now. hda: drive_cmd: status=0x51 { DriveReady SeekComplete Error } hda: drive_cmd: error=0x04 { DriveStatusError } hdc: drive_cmd: status=0x51 { DriveReady SeekComplete Error } hdc: drive_cmd: error=0x04 { DriveStatusError } This seems a little suspicious too but don't know what to make of this either Tonight I will try installing 9.0 again on the problem PC so I look at that again. I will look at the output of dmesg and hdparm with the 9.0. Any suggestions? Damon Register
