Hi Glenn, Have already fixed that problem? Your tests were on the same hardware? I´ve tested two of my boxes one with, FBSD 4.9 and another with the latest cvs 5.4. They´re not the same hardware but the performance with md drive was MUCH faster with 5.4. TE

I have a number of systems running 4.11 that have file backed virtual disks, each of which contains a jail. I need to start using 5.4 for new servers. The catch is, file backed virtual disks using md(4) seem to be much slower than similar virtual disks on 4.11 using vn(4). vn(4) on 4.11
