ZFS-FUSE Bonnie++ benchmark update

After the previous benchmark of btrfs I thought it’d be interesting to revisit ZFS using FUSE under Linux, so after updating to the current tip (02d648b1676c) in the Mercurial trunk I created a 30GB LVM volume for testing and gave it a go. Now you can’t compare it to previous results as this is completely different hardware, but the numbers look quite respectable in comparison to the in-kernel file systems tested yesterday.

Hi Chris,
Interesting..
Any chance you can repeat the test with the current tip?
I’ve just landed async I/O support, which should provide better performance.
With the current tip, you’ll need to install libaio and libaio-dev(el) packages to compile and run zfs-fuse (I haven’t added config checks yet).
Cheers,
Ricardo

Hi Riccardo,
I’ve actually already got that build and ready to go, but am hampered by the fact that my RAID-1 mirror is re-synchronising after what appeared to be an RCU related panic on shutdown last night - the joys of RC kernels!
