This is the OpenBenchmarking.org result file for tests of EXT4 and Btrfs from the Linux 2.6.35, 2.6.37, and 2.6.38-rc6 kernels. Testing was with a System76 Serval Professional notebook with an Intel Quad-Core Sandy Bridge Mobile CPU, 8GB of RAM, 80GB Intel SSD, NVIDIA graphics, and much more.
So go forth to OpenBenchmarking.org and experiment in analyzing the results, merging the results, running up your own comparisons, etc. Share your experiences as OpenBenchmarking.org comments on those results or within the Phoronix Forums.
For those in Los Angeles today at the Southern California Linux Expo, attend our talk where we officially lift the lid on Phoronix Test Suite 3.0 and OpenBenchmarking.org.
