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.
Was the docker container built on fedora? Could it be an issue in our MySQL package? Fedora workstation and server default to BTRFS and XFS, respectively, so perhaps a bug made its way through.
