This skips a compare\nand a branch; although it is easily predictable, it is still\na few cycles on a fast path that we would like to get rid of.\n\nBenchmarking this yields very confusing results. On open-source\nGCC 4.8.1 on Haswell, we get exactly the expected results; the\nbenchmarks where we hit the fast path for literals (in particular\nthe two HTML benchmarks and the protobuf benchmark) give very nice\nspeedups, and the others are not really affected.\n\nHowever, benchmarks with Google\u0027s GCC branch on other hardware\nis much less clear. It seems that we have a weak loss in some cases\n(and the win for the “typical” win cases are not nearly as clear),\nbut that it depends on microarchitecture and plain luck in how we run\nthe benchmark. Looking at the generated assembler, it seems that\nthe removal of the if causes other large-scale changes in how the\nfunction is laid out, which makes it likely that this is just bad luck.\n\nThus, we should keep this change, even though its exact current impact is\nunclear; it\u0027s a sensible change per se, and dropping it on the basis of\nmicrooptimization for a given compiler (or even branch of a compiler)\nwould seem like a bad strategy in the long run.\n\nMicrobenchmark results (all in 64-bit, opt mode):\n\n Nehalem, Google GCC:\n\n Benchmark Base (ns) New (ns) Improvement\n ------------------------------------------------------------------------------\n BM_UFlat/0 76747 75591 1.3GB/s html +1.5%\n BM_UFlat/1 765756 757040 886.3MB/s urls +1.2%\n BM_UFlat/2 10867 10893 10.9GB/s jpg -0.2%\n BM_UFlat/3 124 131 1.4GB/s jpg_200 -5.3%\n BM_UFlat/4 31663 31596 2.8GB/s pdf +0.2%\n BM_UFlat/5 314162 308176 1.2GB/s html4 +1.9%\n BM_UFlat/6 29668 29746 790.6MB/s cp -0.3%\n BM_UFlat/7 12958 13386 796.4MB/s c -3.2%\n BM_UFlat/8 3596 3682 966.0MB/s lsp -2.3%\n BM_UFlat/9 1019193 1033493 953.3MB/s xls -1.4%\n BM_UFlat/10 239 247 775.3MB/s xls_200 -3.2%\n BM_UFlat/11 236411 240271 606.9MB/s txt1 -1.6%\n BM_UFlat/12 206639 209768 571.2MB/s txt2 -1.5%\n BM_UFlat/13 627803 635722 641.4MB/s txt3 -1.2%\n BM_UFlat/14 845932 857816 538.2MB/s txt4 -1.4%\n BM_UFlat/15 402107 391670 1.2GB/s bin +2.7%\n BM_UFlat/16 283 279 683.6MB/s bin_200 +1.4%\n BM_UFlat/17 46070 46815 781.5MB/s sum -1.6%\n BM_UFlat/18 5053 5163 782.0MB/s man -2.1%\n BM_UFlat/19 79721 76581 1.4GB/s pb +4.1%\n BM_UFlat/20 251158 252330 697.5MB/s gaviota -0.5%\n Sum of all benchmarks 4966150 4980396 -0.3%\n\n\n Sandy Bridge, Google GCC:\n \n Benchmark Base (ns) New (ns) Improvement\n ------------------------------------------------------------------------------\n BM_UFlat/0 42850 42182 2.3GB/s html +1.6%\n BM_UFlat/1 525660 515816 1.3GB/s urls +1.9%\n BM_UFlat/2 7173 7283 16.3GB/s jpg -1.5%\n BM_UFlat/3 92 91 2.1GB/s jpg_200 +1.1%\n BM_UFlat/4 15147 14872 5.9GB/s pdf +1.8%\n BM_UFlat/5 199936 192116 2.0GB/s html4 +4.1%\n BM_UFlat/6 12796 12443 1.8GB/s cp +2.8%\n BM_UFlat/7 6588 6400 1.6GB/s c +2.9%\n BM_UFlat/8 2010 1951 1.8GB/s lsp +3.0%\n BM_UFlat/9 761124 763049 1.3GB/s xls -0.3%\n BM_UFlat/10 186 189 1016.1MB/s xls_200 -1.6%\n BM_UFlat/11 159354 158460 918.6MB/s txt1 +0.6%\n BM_UFlat/12 139732 139950 856.1MB/s txt2 -0.2%\n BM_UFlat/13 429917 425027 961.7MB/s txt3 +1.2%\n BM_UFlat/14 585255 587324 785.8MB/s txt4 -0.4%\n BM_UFlat/15 276186 266173 1.8GB/s bin +3.8%\n BM_UFlat/16 205 207 925.5MB/s bin_200 -1.0%\n BM_UFlat/17 24925 24935 1.4GB/s sum -0.0%\n BM_UFlat/18 2632 2576 1.5GB/s man +2.2%\n BM_UFlat/19 40546 39108 2.8GB/s pb +3.7%\n BM_UFlat/20 175803 168209 1048.9MB/s gaviota +4.5%\n Sum of all benchmarks 3408117 3368361 +1.2%\n\n\n Haswell, upstream GCC 4.8.1:\n\n Benchmark Base (ns) New (ns) Improvement\n ------------------------------------------------------------------------------\n BM_UFlat/0 46308 40641 2.3GB/s html +13.9%\n BM_UFlat/1 513385 514706 1.3GB/s urls -0.3%\n BM_UFlat/2 6197 6151 19.2GB/s jpg +0.7%\n BM_UFlat/3 61 61 3.0GB/s jpg_200 +0.0%\n BM_UFlat/4 13551 13429 6.5GB/s pdf +0.9%\n BM_UFlat/5 198317 190243 2.0GB/s html4 +4.2%\n BM_UFlat/6 14768 12560 1.8GB/s cp +17.6%\n BM_UFlat/7 6453 6447 1.6GB/s c +0.1%\n BM_UFlat/8 1991 1980 1.8GB/s lsp +0.6%\n BM_UFlat/9 766947 770424 1.2GB/s xls -0.5%\n BM_UFlat/10 170 169 1.1GB/s xls_200 +0.6%\n BM_UFlat/11 164350 163554 888.7MB/s txt1 +0.5%\n BM_UFlat/12 145444 143830 832.1MB/s txt2 +1.1%\n BM_UFlat/13 437849 438413 929.2MB/s txt3 -0.1%\n BM_UFlat/14 603587 605309 759.8MB/s txt4 -0.3%\n BM_UFlat/15 249799 248067 1.9GB/s bin +0.7%\n BM_UFlat/16 191 188 1011.4MB/s bin_200 +1.6%\n BM_UFlat/17 26064 24778 1.4GB/s sum +5.2%\n BM_UFlat/18 2620 2601 1.5GB/s man +0.7%\n BM_UFlat/19 44551 37373 3.0GB/s pb +19.2%\n BM_UFlat/20 165408 164584 1.0GB/s gaviota +0.5%\n Sum of all benchmarks 3408011 3385508 +0.7%\n\n\ngit-svn-id: http://snappy.googlecode.com/svn/trunk@78 03e5f5b5-db94-4691-08a0-1a8bf15f6143\n" }, { "commit": "49fc9d934dd7813d755ac69ca29e24e76ae23f80", "tree": "7ddf072a44e0d70c691b98a3457022ae8c45e119", "parents": [ "35372c413ae891b45abc11cf65244a0f8d367d23" ], "author": { "name": "snappy.mirrorbot@gmail.com", "email": "snappy.mirrorbot@gmail.com@03e5f5b5-db94-4691-08a0-1a8bf15f6143", "time": "Fri Jun 14 21:42:26 2013" }, "committer": { "name": "snappy.mirrorbot@gmail.com", "email": "snappy.mirrorbot@gmail.com@03e5f5b5-db94-4691-08a0-1a8bf15f6143", "time": "Fri Jun 14 21:42:26 2013" }, "message": "Make the two IncrementalCopy* functions take in an ssize_t instead of a len,\nin order to avoid having to do 32-to-64-bit signed conversions on a hot path\nduring decompression.

"message": "Increase the Zippy block size from 32 kB to 64 kB, winning ~3% density\nwhile being effectively performance neutral.\n\nThe longer story about density is that we win 3-6% density on the benchmarks \nwhere this has any effect at all; many of the benchmarks (cp, c, lsp, man)\nare smaller than 32 kB and thus will have no effect. Binary data also seems\nto win little or nothing; of course, the already-compressed data wins nothing.\nThe protobuf benchmark wins as much as ~18% depending on architecture,\nbut I wouldn\u0027t be too sure that this is representative of protobuf data in\ngeneral.\n\nAs of performance, we lose a tiny amount since we get more tags (e.g., a long\nliteral might be broken up into literal-copy-literal), but we win it back with\nless clearing of the hash table, and more opportunities to skip incompressible\ndata (e.g. in the jpg benchmark). Decompression seems to get ever so slightly\nslower, again due to more tags. The total net change is about as close to zero\nas we can get, so the end effect seems to be simply more density and no\nreal performance change.\n\nThe comment about not changing kBlockSize, scary as it is, is not really\nrelevant, since we\u0027re never going to have a block-level decompressor without\nexplicitly marked blocks. Replace it with something more appropriate.\n\nThis affects the framing format, but it\u0027s okay to change it since it basically\nhas no users yet.\n\n\nDensity (note that cp, c, lsp and man are all smaller than 32 kB):\n\n Benchmark Description Base (%) New (%) Improvement\n --------------------------------------------------------------\n ZFlat/0 html 22.57 22.31 +5.6%\n ZFlat/1 urls 50.89 47.77

If anything, it\u0027s ever so\nslightly faster.\n\nThis may or may not enable compression of very large blocks (\u003e2^32 bytes)\nwhen size_t is 64-bit, but I haven\u0027t checked, and it is still not a supported\ncase.\n\n\ngit-svn-id: http://snappy.googlecode.com/svn/trunk@56 03e5f5b5-db94-4691-08a0-1a8bf15f6143\n" }, { "commit": "25b79a01ab7d6341ce00fea20b659b31a79bc3fb", "tree": "b08e20aa7287a047b053cee8a0564b7f45803719", "parents": [ "afaa2d147dc3edb2b341eeab18916af842fbe56a" ], "author": { "name": "snappy.mirrorbot@gmail.com", "email": "snappy.mirrorbot@gmail.com@03e5f5b5-db94-4691-08a0-1a8bf15f6143", "time": "Wed Jan 04 10:46:39 2012" }, "committer": { "name": "snappy.mirrorbot@gmail.com", "email": "snappy.mirrorbot@gmail.com@03e5f5b5-db94-4691-08a0-1a8bf15f6143", "time": "Wed Jan 04 10:46:39 2012" }, "message": "Add a framing format description.

(Note that Step() was already inlined,\nso it is not the manual inlining that buys the performance here.)\n\nThe wins are about 3–6% for Core 2, 6–13% on Core i7 and 5–12% on Opteron\n(for plain array-to-array decompression, in 64-bit opt mode).\n\nThere is a tiny difference in the behavior here; if an invalid literal is\nencountered (ie., the writer refuses the Append() operation), ip_ will now\npoint to the byte past the tag byte, instead of where the literal was\noriginally thought to end. However, we don\u0027t use ip_ for anything after\nDecompressAllTags() has returned, so this should not change external behavior\nin any way.\n\nMicrobenchmark results for Core i7, 64-bit (Opteron results are similar):\n\nBenchmark Time(ns) CPU(ns) Iterations\n---------------------------------------------------\nBM_UFlat/0 79134 79110 8835 1.2GB/s html [ +6.2%]\nBM_UFlat/1 786126 786096 891 851.8MB/s urls [+10.0%]\nBM_UFlat/2 9948 9948 69125 11.9GB/s jpg [ -1.3%]\nBM_UFlat/3 31999 31998 21898 2.7GB/s pdf [ +6.5%]\nBM_UFlat/4 318909 318829 2204 1.2GB/s html4 [ +6.5%]\nBM_UFlat/5 31384 31390 22363 747.5MB/s cp [ +9.2%]\nBM_UFlat/6 14037 14034 49858 757.7MB/s c [+10.6%]\nBM_UFlat/7 4612 4612 151395 769.5MB/s lsp [ +9.5%]\nBM_UFlat/8 1203174 1203007 582 816.3MB/s xls [+19.3%]\nBM_UFlat/9 253869 253955 2757 571.1MB/s txt1 [+11.4%]\nBM_UFlat/10 219292 219290 3194 544.4MB/s txt2 [+12.1%]\nBM_UFlat/11 672135 672131 1000 605.5MB/s txt3 [+11.2%]\nBM_UFlat/12 902512 902492 776 509.2MB/s txt4 [+12.5%]\nBM_UFlat/13 372110 371998 1881 1.3GB/s bin [ +5.8%]\nBM_UFlat/14 50407 50407 10000 723.5MB/s sum [+13.5%]\nBM_UFlat/15 5699 5701 100000 707.2MB/s man [+12.4%]\nBM_UFlat/16 83448 83424 8383 1.3GB/s pb [ +5.7%]\nBM_UFlat/17 256958 256963 2723 684.1MB/s gaviota [ +7.9%]\nBM_UValidate/0 42795 42796 16351 2.2GB/s html [+25.8%]\nBM_UValidate/1 490672 490622 1427 1.3GB/s urls [+22.7%]\nBM_UValidate/2 237 237 2950297 499.0GB/s jpg [+24.9%]\nBM_UValidate/3 14610 14611 47901 6.0GB/s pdf [+26.8%]\nBM_UValidate/4 171973 171990 4071 2.2GB/s html4 [+25.7%]\n\n\n\n\ngit-svn-id: http://snappy.googlecode.com/svn/trunk@38 03e5f5b5-db94-4691-08a0-1a8bf15f6143\n" }, { "commit": "5258607248a000affb2f72b87b9bbd044806677d", "tree": "a6c4c2ef2bc94b5fcc30495ce743273ed7bf3e96", "parents": [ "184f228f1c37b4e6b18051b6b601d23f1ca364ef" ], "author": { "name": "snappy.mirrorbot@gmail.com", "email": "snappy.mirrorbot@gmail.com@03e5f5b5-db94-4691-08a0-1a8bf15f6143", "time": "Tue May 17 08:48:25 2011" }, "committer": { "name": "snappy.mirrorbot@gmail.com", "email": "snappy.mirrorbot@gmail.com@03e5f5b5-db94-4691-08a0-1a8bf15f6143", "time": "Tue May 17 08:48:25 2011" }, "message": "\nFix the numbering of the headlines in the Snappy format description.\n\nR\u003dcsilvers\nDELTA\u003d4 (0 added, 0 deleted, 4 changed)\n\n\nRevision created by MOE tool push_codebase.\nMOE_MIGRATION\u003d1906\n\n\ngit-svn-id: http://snappy.googlecode.com/svn/trunk@37 03e5f5b5-db94-4691-08a0-1a8bf15f6143\n" }, { "commit": "184f228f1c37b4e6b18051b6b601d23f1ca364ef", "tree": "325b3e3e227e9ac961ac8d7602413fadb2cd2c06", "parents": [ "f9c515d1c3f8ea5ca437291bf2ea17470eaf5316" ], "author": { "name": "snappy.mirrorbot@gmail.com", "email": "snappy.mirrorbot@gmail.com@03e5f5b5-db94-4691-08a0-1a8bf15f6143", "time": "Mon May 16 08:59:18 2011" }, "committer": { "name": "snappy.mirrorbot@gmail.com", "email": "snappy.mirrorbot@gmail.com@03e5f5b5-db94-4691-08a0-1a8bf15f6143", "time": "Mon May 16 08:59:18 2011" }, "message": "\nFix public issue #32: Add compressed format documentation for Snappy.\nThis text is new, but an earlier version from Zeev Tarantov was used\nas reference.\n\nR\u003dcsilvers\nDELTA\u003d112 (111 added, 0 deleted, 1 changed)\n\n\nRevision created by MOE tool push_codebase.\nMOE_MIGRATION\u003d1867\n\n\ngit-svn-id: http://snappy.googlecode.com/svn/trunk@36 03e5f5b5-db94-4691-08a0-1a8bf15f6143\n" }, { "commit": "f9c515d1c3f8ea5ca437291bf2ea17470eaf5316", "tree": "2dc204820493a5a14684fcfd32a3d15be07985a8", "parents": [ "3a172157f6113b748b37a3bc231af8c39c69210f" ], "author": { "name": "snappy.mirrorbot@gmail.com", "email": "snappy.mirrorbot@gmail.com@03e5f5b5-db94-4691-08a0-1a8bf15f6143", "time": "Mon May 09 21:29:02 2011" }, "committer": { "name": "snappy.mirrorbot@gmail.com", "email": "snappy.mirrorbot@gmail.com@03e5f5b5-db94-4691-08a0-1a8bf15f6143", "time": "Mon May 09 21:29:02 2011" }, "message": "\nFix public issue #39: Pick out the median runs based on CPU time,\nnot real time.
