I'm not so sure it is not related.

I was just now trying RAID1 on a standard debian wheezy kernel. I was 
gettng around 220 fsyncs/sec

I then installed the latest pve kernel:
FSYNCS/SECOND:     3991.22

I'm now changing it to RAID10.

My test machine is different hardware though, and the production 
machines are running the pve kernels, but also an older version: 
Driver                                   : 1.2-1 (29900)

These are still running a pve 2.3 release. I haven't had the opportunity 
to upgrade yet.

I'll try running the older kernel on the test machine.

Thanks Martin! I have a lead to salvation now :-)
