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.
