These (for obvious reasons) were performed on the same system as the
others were in my previous reply:
# time ~/lzma-4.32.7/src/lzma/lzma linux-2.6.26.3-olpc.tar
real 9m26.749s
user 9m19.044s
sys 0m0.807s
# ls -lh
-rw-r----- 1 turtle turtle 74M Sep 17 02:11 linux-2.6.26.3-olpc.tar.lzma
# time ~/lzma-4.32.7/src/lzma/lzma -d linux-2.6.26.3-olpc.tar.lzma
real 0m16.384s
user 0m10.643s
sys 0m1.127s
The lzma utils just barely squeezes past lzip in performance in all
cases, including size.
