A shoutout to lz4

#1

Post by dreamer » Mon Jan 14, 2019 12:08 am

I was making snapshots with lzo compression. It took about an hour with one processor core. ISO size around 2,7 GB. Then I decided to try lz4 instead. Amazing speed, an hour became not much more than 6 minutes, so almost a 90 % reduction of ISO creation time. ISO size went from 2,7 to 3,2 GB.

I think some MX Snapshot update reset my config, but my successful config (for low power machines) had two entries like this (in /etc/mx-snapshot.conf):

Code: Select all

mksq_opt=-comp lz4 -processors 1
Unless you want to distribute your ISOs I don't think ISO size is a problem so it can be worth making them bigger and put less strain on your poor little machine (and make them run faster in live-mode?). If you make them on a powerful machine you don't have to worry and can use standard settings.
