The SQLite database performance had regressed under Btrfs in the Linux 3.1 kernel, but that has been fixed in Linux 3.2 and is back to nearly where it was at in Linux 3.0.

The PostMark mail server database performance is still slower than where it was at in Linux 3.0.

When running six Dbench clients simultaneously, the reported Btrfs performance is much faster than in Linux 3.1 and Linux 3.0. Btrfs in Linux 3.2 is nearly three times faster than the two earlier kernels, but based upon the result (620MB/s), a change in Btrfs for Linux 3.2 is causing the clients to no longer sync to disk and appear to be running in RAM.

With 12 Dbench clients, this was seen as well with the disk result no longer being accurate under Linux 3.2.
