From fd53fee04b1f1c1ca1e30e8d470d7416900a35dc Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Zbigniew=20J=C4=99drzejewski-Szmek?= Date: Sat, 5 Jul 2014 14:29:56 -0400 Subject: compress: add benchmark-style test This is useful to test the behaviour of the compressor for various buffer sizes. Time is limited to a minute per compression, since otherwise, when LZ4 takes more than a second which is necessary to reduce the noise, XZ takes more than 10 minutes. % build/test-compress-benchmark (without time limit) XZ: compressed & decompressed 2535300963 bytes in 794.57s (3.04MiB/s), mean compresion 99.95%, skipped 3570 bytes LZ4: compressed & decompressed 2535303543 bytes in 1.56s (1550.07MiB/s), mean compresion 99.60%, skipped 990 bytes % build/test-compress-benchmark (with time limit) XZ: compressed & decompressed 174321481 bytes in 60.02s (2.77MiB/s), mean compresion 99.76%, skipped 3570 bytes LZ4: compressed & decompressed 2535303543 bytes in 1.63s (1480.83MiB/s), mean compresion 99.60%, skipped 990 bytes It appears that there's a bug in lzma_end where it leaks 32 bytes. --- .gitignore | 1 + 1 file changed, 1 insertion(+) (limited to '.gitignore') diff --git a/.gitignore b/.gitignore index 9523ea027..822f5a6ff 100644 --- a/.gitignore +++ b/.gitignore @@ -142,6 +142,7 @@ /test-cgroup-mask /test-cgroup-util /test-compress +/test-compress-benchmark /test-conf-files /test-coredump-vacuum /test-daemon -- cgit v1.2.3
