Wow. Just seeing this. I've not done proper benchmarking yet but rn we are lagging behind in file I/O for the OverlayFS impl





There was a period where NFS was faster, particularly on windows and OSX where you were paying a double indirection.

Overlays are always tough because docker doesn’t like you writing to the filesystem in the first place. The weapon if first result is deflection; tell them not to do it.

I had to put up with an old docker version that leaked overlay data for quite a while before we moved off prem.
