read/write benchmarking: UFS2 vs ZFS vs EXT3 vs ZFS RAIDZ vs Linux MDRAID

[Andrew Snow]

OK, I thought we were taling about a single-threaded sequential write 
which was what my benchmark is. It sounds like the graphs you published 
were of a multi-threaded writers - how many processes were running in 
parallel in the case of the "Contiguous Write Performance"  here?
