It seems that when using overlay2 storage driver, docker is much slower when using a LVM compared to without a LVM (ext4 filesystem in both cases, same machine).

Questions:

  1. Is this intended/expected?
  2. Is a LVM a recommended setup for docker usage?
  3. Is it worth to try other storage drivers (e.g. devicemapper with direct-lvm)?

I'm not an docker expert, just responding from my experience and limited knowledge.

  1. It's expected, yes.
  2. That's a matter of opinion. I'd say no, but that's very subjective.
  3. Yes.
