Threadzip performed 10x faster (hardly a performance I expect from lzop) and

The key is multiple cores. I'm on an 8-core xeon.
I am glad to see that you found a use for all those cores.
As a simple test here, on AMD64 and Solaris 10 I see 3.6X less CPU
consumption from 'lzop -3' than from 'gzip -3'. With lots of
background activity (zfs scrub of the pool), this increases to a 4X
advantage.
