Thanks Jeff, I've had a look at that page and even though it seems to be aimed at ssd's it is still useful. My main performance issue is fragmentation impacting rpsmiss and seeks. I've read that fragmentation on journaling file systems like EXT4 is a non-issue, but I don't know why, and I haven't seen anything to indicate whether or not BTRFS is similar.On Sat, Nov 16, 2024 at 7:22 PM Stephen Morris <steve.morris.au@xxxxxxxxx> wrote:To test my hard disk performance I have run Kdiskmark and used the Real World Performance Profile. For its sequential read performance it is showing around 156 MB/s on my ST3000DM007-1WY1 (3TB Seagate Barracuda), which given that device support 1/3/6 Gb/s I/O speeds and the device is plugged into a 6Mb/s Sata port on the motherboard, is very poor performance. Doing some research on disk performance I found a reference to bad disk performance be attributable to BTRFS and that the disk should be formatted as EXT4, is this sentiment reasonable and if so why is Fedora pushing the use of BTRFS.You might also have a look at Debian's page at <https://wiki.debian.org/SSDOptimization>. (I am not aware of a similar page for Fedora).
