Hi,

I have a performance problem when setting up drbd 0.7 (svn from last friday, but
also tried with  0.7.16). When I setup a hardware raid5 on the HP machine I get
an initial syncrate from approximatly 2.5-3 MB/sec over a dedicated ethernet
link. (After the raid was synced)
When I configure, on the same machine, a hardware raid1 then I get around 25-30
MB/sec. Same when I configure single disk in the raid controller and let the
linux md driver do the raid5.
Somebody any ideas why the hardware raid5 doesn't work?

Regards,
  Torsten
