I did some tests on 2 different NFS,SMB shares and I had the same very slow
backup performance.
Then I reverted from *pve-kernel-2.6.32-23-pve *to *pve-kernel-2.6.32-20-pve
*and the backup
performance got back to normal speed.

This is completely different virtualization schemes. No, that's not
possible.
Use dpkg --set/get selections to get list of installed packages to get

Hi all,
I'm doing some tests with a Intel SSD 320 300GB disk. This is a 3 Gbps
disk with max ratings of R/W 270/205 MB/s and 39500/23000-400 IOPS.
The disk is attached to a Dell PERC H200 (LSI SAS2008) RAID controller,
no raid, no logical volume, no cache and is mounted as ext4
For SSDs you should set the I/O scheduler to NOOP. Proxmox uses Deadline by
default, which is good for spinning disks, but not for SSDs.
Examples (ssd is sdb):
Get currently used scheduler:
cat /sys/block/sdb/queue/scheduler
noop anticipatory [deadline] cfq
Set scheduler:
echo
Hi Marco,
Thanks for the hint. Fsyncs seem to have improved a little bit:

Hi Michale,
That would risk the data in case of a power failure doesn't it? (yes,
server is UPS backed... :) )

No more risk than with ext3. Ext3 also uses barrier=0 as default option.
