#159 Publicise btrfs performance data
Closed: Deferred to upstream 2 years ago by catanzaro. Opened 2 years ago by aday.

Comment from #153:

We have no performance numbers for desktop/developer workloads. We have anecdotal evidence that it's perceptually identical, but certainly nothing to point to if people say that that F33 is slow/sluggish and blame it on btrfs

A quote from: https://arstechnica.com/gadgets/2020/05/linux-distro-review-fedora-workstation-32/

I initiated a reboot on each VM first—and despite clicking Fedora's reboot button before Ubuntu's, Ubuntu got to the desktop noticeably faster. A similar test with a first launch of Firefox after the reboot also came in quicker on Ubuntu. This confirmed my "seat-of-the-pants" impression on the laptop itself—Fedora can be a bit slower than Ubuntu with some tasks.

We should at the bare minimum be doing this sort of testing ourselves to show that Fedora on btrfs is up to Fedora on ext4, adding in a kernel compile maybe.

@josef mentioned that some work is going on to create a set of comparative performance tests.

Once we have some numbers it will be important to publicise them, probably as a blog post or similar.

Proposal: close this issue and open it under https://pagure.io/fedora-btrfs/project/issues, so it's no longer tracked on the WG issue tracker. Chris, is this OK?

👍 yes
I did a baremetal install of Ubuntu 20.04 and Fedora 32 and once autologin was enabled on Fedora, I get the same boot times as Ubuntu whether Fedora is LVM+ext4 or Btrfs. By same, within a couple seconds.
