The Enterprise End User Summit is an exclusive invitation-only event that brings together high performance end users with the highest level Linux community developers. CTOs, architects, senior IT representatives and kernel developers are able to connect directly to advance the features most critical to using Linux in the enterprise.

At the Enterprise End User Summit in 2010, Bhaskar presented results of benchmarking filesystems for datababase performance using the 3n+1 problem on the GT.M database engine. Since that time, xfs and ext4 have been sped up, and btrfs is production grade. This presentation revisits the benchmark to provide updated results with a more recent Linux kernel, and with copy-on-write turned off for brfs. Time permitting, results from the 3n+1 benchmark will also be compared with results from iothrash, a pure ANSI C / POSIX file system benchmark which allows comparison across systems, even those without a GT.M implementation.
The intended audience is technical, those developing filesystems, and tuning filesystem performance, especially for update intensive applications like transaction processing databases.
