jemalloc

[oeresundsgruppen]

Any chance you can amend docker-build to use jemalloc ?

apt-get install -y --no-install-recommends libjemalloc2
ENV LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libjemalloc.so.2

We'd be unlikely to include or activate it by default with the same reason as docker-library/ruby#182 (comment):

Without an explicit upstream recommendation for using jemalloc by default, I hesitate to make an actual image change here (especially given that there are really functional workarounds that allow users to enable jemalloc in a dependent image without too much trouble).

So, this should be done in your own Dockerfile that is FROM MySQL.

Sure I can give it a run, and let you know
