I have created a big tar from linux tree: linux-2.6.tar 300,0 MB Then I have created to compressed files with zip and lzop utility (the latter uses the lzo compression algorithm): linux-2.6.zip 70,1 MB linux-2.6.tar.lzo 108,0 MB Then I have tested the decompression speed: $ time unzip -p linux-2.6.zip > /dev/null 3.95user 0.09system 0:04.05elapsed 99%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+0outputs (0major+189minor)pagefaults 0swaps $ time lzop -d -c linux-2.6.tar.lzo > /dev/null 2.10user 0.07system 0:02.18elapsed 99%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+0outputs (0major+234minor)pagefaults 0swaps So bottom line is that lzo decompression speed is almost the double of zip. Marco P.S: Compression size is better for zip but a more realistic test would be to try with a delta packaged repo instead of a simple tar of source files. Because delta packaged is already compressed in his way perhaps difference in final file sizes is smaller. - To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
