With quite some time having passed since we last benchmarked the Reiser4 file-system, to end out July we have some fresh benchmarks of Reiser4 from the newly released patches for the Linux 3.10 kernel. There's fairly good performance out of the experimental file-system when compared to the original ReiserFS as well as EXT4, Btrfs, and XFS.
On a Linux 3.10.4 vanilla kernel, the Reiser4 patch was applied. From this same kernel the ReiserFS, EXT4, Btrfs, and XFS kernels were tested from a Lenovo ThinkPad W510 notebook with Intel Core i7 720QM processor and 160GB Intel SSD. The tested file-systems from this high-performance solid-state drive were with their stock mount options.
All benchmarking occurred via the open-source Phoronix Test Suite software.
