Real World Benchmarks Of The EXT4 File-System
Switching over to measuring the read performance with IOzone, XFS was able to regain the top spot by a very slim margin. XFS and EXT4 were reading at 57MB/s while EXT3 had sped up to read at 50MB/s and ReiserFS at 39MB/s.
Our third disk test was with the Flexible IO Tester. This test is the least common compared to Bonnie++ and IOzone for disk benchmarking, but the Flexible IO Tester is able to display an array of performance data for disk drives and features a number of different I/O engines. When running the Intel IOMeter File Server Access Pattern example test, ReiserFS had pulled out of last place and it was replaced by XFS being the slowest. EXT4 was the fastest at this test followed by the EXT3 file-system. EXT4 was over three-times faster than XFS.
Now it's time to move onto our tests that are more real world focused.
