Btrfs Benchmarks: Btrfs Is Not Yet The Performance King

Starting with the Parallel BZIP2 compression testing, Btrfs was not the fastest. In fact, at this test, Btrfs was the slowest. It took just 89 seconds to compress a 2GB file using PBZIP2 on an EXT4 file-system, but that quickly expanded to 106 seconds with Btrfs. Even the EXT3 file-system had required less time at 97 seconds and XFS just needed 91 seconds.

When compressing a 256MB file using LZMA compression, all four tested file-systems performed relatively the same.

While more CPU intensive than disk oriented, as a real world indicator, it took roughly the same amount of time no matter the file-system when encoding an audio file into an MP3 format using LAME.
