Phoronix: Btrfs LZO Compression Performance

While the performance of the Btrfs file-system with its default mount options didn't change much with the just-released Linux 2.6.38 kernel as shown by our large HDD and SSD file-system comparison, this new kernel does bring LZO file-system compression support to Btrfs. This Oracle-sponsored file-system has supported Gzip compression for months as a means to boost performance and preserve disk space, but now there's support for using LZO compression. In this article we are looking at the Btrfs performance with its default options and then when using the transparent Zlib and LZO compression.
