Hi, More than one year ago Phillip Lougher proposed LZ4 compression in his squashfs: http://thread.gmane.org/gmane.linux.file-systems/76409 The discussion above shows that people wished that LZ4 support be added to the Linux kernel after it's officially supported by squahsfs-tools. Also, some benchmarks were requested. Version 4.3 of squahsfs-tools, released on 2014-05-12 includes LZ4 support. I have posted my benchmarks in that thread. The HC mode of LZ4 compression came out to be 4x faster (=5x speed) than LZO. The default mode of LZ4 (i.e. the non-high-compression) is ~50x faster than LZO. Decompression speed is also noticeably faster. Not only that applications start faster, but the occasional lags during normal desktop operations on LZO compressed squashfs completely disappeared. So, can we agree now, to merge the LZ4 support of squashfs into mainline?
