Benchmarks Of ZFS-FUSE On Linux Against EXT4, Btrfs

ZFS, regardless of whether it is ZFS-FUSE or ZFS on OpenSolaris, really is slaughtered when it comes to the multi-threaded random writes. Btrfs was 24.47x faster than ZFS-FUSE, which handled random writes at only 5MB/s.

When carrying out an 8GB write test with a 64Kb block size in IOzone, EXT4 and ZFS were 1.64~1.67x faster than ZFS-FUSE.

With the final test, which was an 8GB read using IOzone, the disk read performance results for ZFS-FUSE actually look close to that of EXT4 and Btrfs, but that's as the ZFS module is carrying out some caching on the reads.
