I must say that all the benchmarked filesystem shows very high performance throughout most of the test session. This is a very important achievement especially for BTRFS, which is a relatively young filesystem.
However, some obvious recommendations emerge from the observed patters:
- if you plan to use MySQL or PostgreSQL, use EXT4 as you can not go wrong with it. However, stay away from BTRFS;
- for large file installation (as VM hosting system) or direct I/O, go with XFS.
BTRFS shows some big improvement that are remarkable. However, I will not use it for critical data as it and its fsck are relatively young.
Have a nice day!
