I ran across an interesting page which reviews the performance of a number of compressors which are already available for the Linux Kernel (zlib, lzop, lzma) and which shows the highest performing compressor choice given the authors test CPU for a variety of data transfer rates, and read vs write ratio. http://users.elis.ugent.be/~wheirman/compression/ It shows that for normal disk speeds (i.e. >200mbit/sec) LZOP of some flavor will yield the greatest performance. (LZMA, however, has considerably greater space savings; but isn't likely to increase overall performance with normal disk) -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
