There is no shortage of EXT4 benchmarks from comparing this evolutionary file-system's performance on netbooks to how it battles the Btrfs file-system to its performance recession. In this article though we are finally delivering something that has long been requested and that is Reiser4 file-system benchmarks running directly against EXT4 and Btrfs. We have also thrown in the original ReiserFS file-system for comparison too.
The future of the Reiser4 file-system has been in debate since 2007 and earlier since the file-system's lead developer, Hans Reiser, was sent to prison for murdering his wife in California. As of right now there are no immediate plans to push the Reiser4 file-system into the mainline Linux kernel even as an experimental file-system, but it may aim for inclusion this year as we found out from Edward Shishkin who had taken over much of the Reiser4 development. Reiser4 is designed to be a more efficient journaling file-system than ReiserFS and other Linux file-systems particularly when handling small files, faster support for large directories, provide a plug-in infrastructure for supporting encryption and compression, offer transaction support, and have a dynamically optimized disk layout.
