Compression programs comparison

Filed under: Uncategorized — Tags: , — admin @ 2009-01-24 10:43

I was wondering how powerful are those simple stream compressors like gzip and bzip2. Test rabbit was a Linux kernel source tree tar-ed into one file which was thrown out to those compression beasts. Simple benchmarks were performed on Mobile AMD Sempron 3100+.

Contestants: gzip 1.3.12, bzip2 1.0.4, lzop 1.01, lzma 4.43

Speed results:

time gzip -c linux- >/dev/null
real    0m20.300s
user    0m17.449s
sys     0m0.532s

time gzip -c --fast linux- >/dev/null
real    0m13.581s
user    0m8.837s
sys     0m0.448s

time gzip -c --best linux- >/dev/null
real    0m38.525s
user    0m36.018s
sys     0m0.436s

time lzop -c linux- >/dev/null
real    0m9.791s
user    0m2.964s
sys     0m0.576s

time lzop -c --fast linux- >/dev/null
real    0m10.146s
user    0m3.084s
sys     0m0.564s

time lzop -c --best linux- >/dev/null
real    2m18.935s
user    2m9.952s
sys     0m0.716s

time bzip2 -c linux- >/dev/null
real    2m6.911s
user    1m59.339s
sys     0m0.680s

time lzma -c linux- >/dev/null
real    7m19.071s
user    7m5.579s
sys     0m0.652s
