The Linux 3.0 Kernel With EXT4 & Btrfs

When using the Threaded I/O Tester to test the random write performance with 16 threads of 128MB writes, EXT4 had a very slight advantage on the powerful Intel notebook with the high-performance solid-state drive. Running the slower Pentium M notebook with 5400RPM IDE drive, Btrfs was many times faster than EXT4.

When looking at the 8GB write performance using IOzone, the file-system performance was close for each notebook.

EXT4 did slightly better for both systems when it came to the 8GB read performance.

These results can also be found on OpenBenchmarking.org via the 1106122-GR-1106118GR60 result file for those interested.
