Yepp, seems we've found the error. After changing memory (Kingston ECC) which ran without any errors on memtest rsync-speed seems to be fine (140-180 Mbytes/s). More results next week. Kind regards. EDIT: We've also tried 5405 without any problems.

Hi, reinstallation didn't fix the problem. Now I've temporarily changed hardware and everything runs fine but I've got to use the original server in a few days again.

As I wrote I've already performed those tests without result.

Nothing - really nothing unusual. Tried all offline tests - in theory the machine should be really fast - in fact it ain't. Think there's no help anymore - I'll migrate the vms to my own server and reinstall the broken machine. Thanks for your help.

Thanks for your answer. Yes sure, clean.

Hi Udo, don't think it could be a disk. I've tried my RAID5-Device and a single Disk. Both are slow. Here's the output while running rsync (speed 50-350kb/s) Device: tps MB_read/s MB_wrtn/s MB_read MB_wrtn sda 2,40 0,00 0,20 0...

Additional Information: Concerning. If I create a 1g-size file via dd I loose my ssh-connection.

Hi Udo, thanks for your answer. Here's what happens with an normal rsync (from usb-device to local hdd): sending incremental file list vzdump-qemu-300-2011_01_14-11_58_26.tgz 22380544 0% 338.62kB/s 7:52:01 The values are even getting worse... Here's the output from iostat while...

Hi Tom, ty. It's similar to that contoller: LSI Megaraid SAS 9260-4i. I'm confused because bonnie++, pveperf and so on seem to be right. I'll follow your hint as I head the same idea. Best regards, B.

Thanks for your answer. rsnapshot, samba, ssh, all of them. Regards, B.

Hi @all, using Proxmox VE 1.7 (2.6.32) on an Intel Server (2x E5506, Intel RS2BL040 RAID-Controller, 3x 1TB HD RAID-Edition WD, 8GB RAM) I have incredible performance problems: the disks seem to be very slow, native, in VZ and in KVM. pveperf shows: CPU BOGOMIPS: 34131.93 REGEX/SECOND...
