Phoronix: Linux File-System Benchmarks On The Intel Optane 900P SSD

Earlier this week I presented out initial Linux benchmarks of the Intel Optane 900P SSD with this 3D XPoint memory U.2 solid-state drive delivering incredible performance figures. Those tests were done with EXT4 while in this article are more tests with other mainline Linux file-systems and also testing some of the different mount options.

I kinda hope that ZFS gets mainlined in some meaningful way someday so that we can see ZFS be a member of benchmarks here regularly in the future. I know, there are licensing issues that prevent ZFS from being mainlined, but a man can dream, right?!

It would be great to see some ZFS benchmarks as well, as it's the only other filesystem with a comparable feature set to btrfs.

Performance isn't everything.

Michael, would it be possible to get ext2 numbers as well to see whether disabling journaling boosts performance?

while the technique makes sense for disk and flash, these optane drives don't seem to care about locality the way disks do, and don't have issues with write in place like flash, so journaling is causing 2x writes on every metadata operation with no pay off.

If i'm not mistaken, ZFS will never be mainlined over licensing incompatibility...

Oracle recently talked about changing ZFS' license so it could get in the Linux kernel.

Typos:

with the 250GB Intel Optane 900P U.2 SSD.

(it's 280GB)

F2FS and EXT4 were the fastest in discard/nobbarrier modes

If Oracle was to GPL ZFS today, I'm certain it would take at least 5 kernel cycles to get the code into shape for mainline. You'd be looking at a year at least.

Reading is fundamental.

That thing looks like it almost needs active cooling. There may be a use for those hdd water bocks after all.
