== A crude CPU benchmark using lossless compression algorithms == === How to test === {{{ time lzop >/dev/null <testfile time gzip >/dev/null <testfile time bzip2 >/dev/null <testfile time xz >/dev/null <testfile }}} "testfile" is a 175MB avi (southpark_12x12_about_last_night.avi). It's not actually compressible, but it doesn't matter. === Results === || **Hostname** || **System** || ** CPU Brand** || **CPU** ||**Clock**||**Arch**|| **OS** || || xyzzy.cam || Dell T3500 || Intel(R) Xeon(R) CPU || W3690 || 3.47GHz || x86_64 || || || xyzzy.i || XEN || Intel(R) Xeon(R) CPU || X5679 || 3.20GHz || x86_64 || || || giskard-x230 || Lenovo X230 || Intel(R) Core(TM) i5 || 3320M || 2.60GHz || x86_64 || Ubuntu 14.04 || || giskard-x220 || Lenovo X220 || Intel(R) Core(TM) i5 || 2520M || 2.50GHz || x86_64 || Ubuntu 14.04 || || glaptop-x220 || Lenovo X220 || Intel(R) Core(TM) i5 || 2520M || 2.50GHz || x86_64 || || || giskard-x201 || Lenovo X201 || Intel(R) Core(TM) i7 CPU || M 620 || 2.67GHz || x86_64 || || || istek || Lenovo X201 || Intel(R) Core(TM) i5 CPU || M 540 || 2.53GHz || x86_64 || || || r2d2 || PowerEdge R410 || Intel(R) Xeon(R) CPU || E5520 || 2.27GHz || x86_64 || || || ummak || Lenovo Laptop || Intel(R) Core(TM)2 Duo CPU || T9300 || 2.50GHz || x86_64 || || || groucho || || Intel(R) Core(TM)2 || Q6600 || 2.40GHz || x86_64 || || || asus-m2avm || ASUS M2-AVM || AMD Athlon 64 X2 || 5600+ || 2.90GHz || x86_64 || || || triton || || AMD Quad-Core Opteron || 2374 HE || 2.21GHz || x86_64 || || || sroselli || Lenovo x200s || Intel(R) Core(TM)2 Duo CPU || L9400 || 1.80GHz || x86_64 || || || helios || || Intel(R) Core(TM)2 Duo CPU || P7350 || 2.00GHz || x86_64 || || || sunjammer || XEN || AMD Dual-Core Opteron || 2216 HE || 2.41GHz || x86_64 || || || treehouse || Supermicro || AMD Opteron 2214HE || || 2.20GHz || x86_64 || || || beamrider || KVM || AMD Dual-Core Opteron || 2214 HE || 2.20GHz || x86_64 || || || trinity || Supermicro || Intel(R) Core(TM)2 CPU || 6400 || 2.13GHz || i386 || || || bender || Desktop PC || Intel(R) Core(TM)2 CPU || 6300 || 1.86GHz || x86_64 || || || sunjammerold || XEN || ??? || || ??? || x86_64 || || || buildslave4 || XEN || AMD Quad-Core Opteron || 2347HE || 1.90GHz || x86_64 || || || giskard-x200s || Lenovo x200s || Intel(R) Core(TM)2 Duo CPU || U9300 || 1.20GHz || x86_64 || || || loongson || Yeelong || MIPS || || || mipsel || || || dfarning || IdeaPad Y650 || Intel(R) Core(TM)2 Duo CPU || P8700 || 2.53GHz || x86_64 || || ==== Time (seconds) ==== || **Hostname** ||**lzop**||**gzip**||**bzip2**||**lzma** || **xz** ||**index**|| || xyzzy.cam || 0.228 || 5.375 || 29.697 || || 60.827 || || || giskard-x230 || 0.199 || 6.418 || 26.125 || || 67.543 || || || xyzzy.i || 0.255 || 7.056 || 36.174 || || 73.280 || || || giskard-x220 || 0.219 || 6.826 || 28.311 || || 72.894 || || || glaptop-x220 || 2.622 || 6.058 || 31.523 || || 72.578 || || || giskard-x201 || 2.960 || 6.952 || 37.157 || 97.508 || 95.945 || 2.213 || || istek || || 7.550 || 35.480 || || 103.210 || || || r2d2 || 3.896 || 9.029 || 37.652 || 84.727 || 84.554 || || || ummak || 3.790 || 9.231 || 36.311 || 94.530 || || 2.247 || || dfarning || 4.041 || 9.963 || 42.631 || 104.108 || 105.507 || || || groucho || 4.259 || 12.394 || 56.541 || 158.497 || || || || asus-m2avm || 4.101 || 10.104 || 66.804 || 201.453 || || || || triton || 4.445 || 11.363 || 58.886 || 107.545 || || || || sroselli || 5.029 || 12.368 || 48.520 || 113.379 || 108.542 || || || helios || 5.299 || 12.571 || 50.886 || 115.713 || || || || sunjammer || 5.088 || 12.675 || 71.956 || 130.412 || 154.248 || || || treehouse || || 12.551 || 76.207 || 139.021 || 150.076 || || || beamrider || 5.225 || 13.094 || 77.227 || 139.882 || 155.931 || || || trinity || 5.196 || 15.462 || 61.448 || 212.371 || || 1.000 || || bender || 5.516 || 16.163 || 62.373 || 201.685 || || || || sunjammerold || 9.196 || 13.019 || 85.394 || 216.806 || || || || buildslave4 || 9.693 || 18.990 || 73.788 || 202.622 || || || || giskard-x200s || 7.852 || 19.865 || 89.311 || 266.837 || 153.761 || 0.796 || || loongson || 20.918 || 72.245 || 314.057 || 629.609 || || || ==== MB/s ==== || trinity || 33.68 || 12.10 || 2.85 || 0.82 || || || || giskard-x201 || || || || || 4.44 || || || glaptop-x220 || 754.31 ||  25.87 ||   5.87 ||    2.53 ||   2.30 ||        || ==== Notes ==== * all targets using 1 core only! * "index" is xz compression performance relative to gzip (probably) * is xz faster or slower than lzma?
