Nice to see gvinum get's the facelift it so desperately needed. It's 
unfortunate gvinum was never able to recover from the GEOM-age, until 
now maybe. :-)

However, do you think that it's performance is affected too? Last time i 
tested, i was not impressed with gvinum's RAID5 performance, write 
speeds were very low. RAID0 and RAID1 appeared to be on par with gstripe 
and gmirror though. I guess gvinum is primary for people who feel 
comfortable with its configuration and user-interface.

I will be able to test this on my new test system, coming Wedsnesday. 
This consists of a modern dualcore AMD 3GHz processor with 4GB RAM and 8 
SATA disks. If you like, i can report my findings to the list when i'm done.
