Description Aakash Jain 2019-03-22 11:24:54 PDT
Buildbot by default use ‘gz’ for log compression (this is used by default even if we don’t configure logCompressionMethod in master.cfg).

lz4 is much faster than gz (~10x faster). 6MB/s vs 77MB/s at http://docs.buildbot.net/latest/manual/configuration/global.html#log-handling

We should switch to lz4 to improve performance.
