Minchan Kim cd59c2ec5f squashfs: Enhance parallel I/O ... Now squashfs have used for only one stream buffer for decompression so it hurts parallel read performance so this patch supports multiple decompressor to enhance performance parallel I/O. Four 1G file dd read on KVM machine which has 2 CPU and 4G memory. dd if=test/test1.dat of=/dev/null & dd if=test/test2.dat of=/dev/null & dd if=test/test3.dat of=/dev/null & dd if=test/test4.dat of=/dev/null & old : 1m39s -> new : 9s * From v1 * Change comp_strm with decomp_strm - Phillip * Change/add comments - Phillip Signed-off-by: Minchan Kim <minchan@kernel.org> Signed-off-by: Phillip Lougher <phillip@squashfs.org.uk>		2013-11-20 03:35:18 +00:00
