~/comptest $ time lzma e comp39d.tar comp39d.tar.lz
7m5.59s real 6m54.79s user 0m0.59s system
(maximum RAM used: around 80M, I think)
Comments:
rzip and lzma turned in some good numbers (REALLY good numbers),
The lzma package is useless.
Although the algorithm is also LZMA, every time I tried, p7zip was better.
2x faster and always with greater compression (both at max compression level).

Sure, LZMA compression needs memory, though.
