Btrfs File-System Tuning On Linux 3.7

The best performance improvements out of tuning the Btrfs mount options came from using "nodatacow" and LZO compression. Using nodatacow is potentially unsafe since it's not doing copy-on-write for new data, so if something goes wrong you may only have a partial file to recover. With the LZO compression, the results are impressive while it can be regarded as a "safe" tunable and should work out fine for most any users with semi-recent hardware where the CPU wouldn't be taxed with the file-system compression/decompression work.
