16-Way Linux OS Performance Comparison
With all of the Linux distributions using the EXT4 file-system and generally being within a few revisions of each other, there's nothing major to see out of the PostMark mail server disk benchmark.
As shown in the 11-way comparison, Mageia 3 seems to remain in its own class as far as performance is concerned. For some reason, Mageia 3 is much slower than all of the other tested Linux distributions for many of the CPU-intensive benchmarks.
