Hey there. I’ve been using Fedora 33 for quite some time right now and I since I often switch distributions, I’ve noticed that Fedora’s performance isn’t top-notch, heck, it isn’t even close to the “competitors”. Here’s what I am talking about.
I do my daily web development using Docker. Before Fedora 33 got an official repository for Docker CE, I’ve used moby-engine, but performance is more or less the same.
MySQL (native) and Docker are having really bad I/O performance. I don’t want this thread to be too long, but here’s what’s the problem:
That’s weird that docker would slow down that much on EXT4. May be worth a bug report. If you have the time, I would also recommend podman and see if the issue persists with it. It is almost completely docker compatible, and tends to work better around the general red hat platform.
