Description
I tested it briefly, and it looks to me like the time savings of gzip are probably worth the loss of space efficiency, at least for manual runs:
uncompressed size: -rw-r--r-- 1 gregf gregf 7.7G Jul 28 15:08 client.0.log bzip2 gregf@kai:~/logs/testing/logs/remote/ubuntu@sepia57.ceph.dreamhost.com/log$ time bzip2 client.0.log real 34m38.039s user 34m1.828s sys 0m5.064s -rw-r--r-- 1 gregf gregf 366M Jul 28 15:08 logs/remote/ubuntu@sepia57.ceph.dreamhost.com/log/client.0.log.bz2 unzip time: gregf@kai:~/logs/testing$ time bunzip2 logs/remote/ubuntu@sepia57.ceph.dreamhost.com/log/client.0.log.bz2 real 3m54.328s user 3m40.122s sys 0m9.205s gzip: zip time: real 2m45.367s user 2m32.730s sys 0m4.708s -rw-r--r-- 1 gregf gregf 624M Jul 28 15:08 client.0.log.gz unzip time: real 1m48.129s user 0m44.915s sys 0m6.476s
But we should discuss it before we make any changes.
