We looked at using gzip compression with zfs for a backup solution. Short 
answer on our conclusion is it will not work. The gzip -9 compression just 
can't sustain a large throughput of copying gigs of files. We ended up doing 
non gzip compression and taking the hit on compression ratio (1.2x or so 
instead of almost 3x).

In the mean time, we are working on integrating our gzip board into zfs so that 
we can try again with hardware compression.
