When switching to the 4GB read testing using IOzone, the five file-systems performed close to the same speeds on the Samsung NC10 with OCZ Core Series V2 SSD. EXT4 remained the fastest with 102.72MB/s reads compared to XFS at 101.99MB/s, ReiserFS at 99.54MB/s, JFS at 98.69MB/s, and EXT3 at 98.15MB/s.
In our final test we have the Flexible IO Tester. Using the Intel IOMeter File Server Access Pattern resulted in another win for EXT4. EXT4 was noticeably faster than its competitors by a significant lead. Behind EXT4 was ReiserFS followed by XFS, EXT3, and JFS.
These results should not come as much of a surprise considering our previously published EXT4 benchmarks, but it goes to show the EXT4 performance on Ubuntu with the Linux 2.6.28 kernel and the leads that can be spotted even with an Atom-powered netbook using a multi-layer cell SSD for storage. EXT4 was the fastest file-system at the Bork File Encrypter, IOzone, and Flexible IO Tester.
Those interested in testing out EXT4 with Ubuntu can do so using one of the daily ISO spins or starting with Ubuntu 9.04 Alpha 3. For those interested in benchmarking their Linux systems be sure to check out the Phoronix Test Suite.
