[Linuxppc-users] Poor RAID6 performance (vpermxor8 0 MB/s)

[dftxbs3e at free.fr]

Hello,

My RAID6 array has been suffering quite poor write performance (26MB/s), 
using RAID1 does not have that write performance loss. While I do know 
RAID6 causes a write performance hit, I would expect better.

I have noticed this in my dmesg kernel log:

[  255.514795] raid6: using algorithm vpermxor8 gen() 0 MB/s
[  255.514800] raid6: using intx1 recovery algorithm

Is that a bug?

Thanks
