True, I can't get the mover to move my VM img. But the docker.img itself is on the cache. Does having any files from the system share (even if they're not docker related) on the array affect Docker performance?

Here are the diagnostics in case it's needed... diagnostics-20210930-1243.zip

So I recently added a Wordpress docker container and I'm getting horrible performance. Pages take 3 to 8 seconds or more to render (all the time is in TTFB accoring to Chrome). Even the favicon.ico takes 4 seconds! So I installed the container from the official source with the following mappings (pretty standard): `/var/www/html` is mapped to a folder on the 'appdata' share, which is set to `Cache: prefer` (My cache disk is a Samsung 980 250GB PCIe M2 SSD, so plenty fast) The database settings point to a MySQL docker, hosted on the same Unraid, with the DB data also mapped to a folder on the 'appdata' share. I'm running on a HPE DL380p with dual Intel Xeon E5-2697 V2's (48 cores total @ 2.70GHz) so CPU power should also not be an issue. Am I missing something?
