Mysql Dump Splitter / Benchmarks

Just a quick post to let you know some interesting finding on the sql splitter script i wrote: The gzip compressed size 1.2G dump.sql.gz The decompressed size 6.4G dump.sql Time taken in seconds splitter dump.sql gzip -- 22 ./splitter dump.sql.gz gzip -- 29 ./splitter dump.sql -- 43 The limiting factors looks to be the cpu with the gzip to gzip as php only runs on one core. Where as uncompressed to uncompressed was IO wait.
