From 535ed9223dcb32bf90ead5b2c95052838b780620 Mon Sep 17 00:00:00 2001 From: Gavin Andresen Date: Thu, 24 Sep 2015 13:13:38 -0400 Subject: Simple benchmarking framework Benchmarking framework, loosely based on google's micro-benchmarking library (https://github.com/google/benchmark) Wny not use the Google Benchmark framework? Because adding Even More Dependencies isn't worth it. If we get a dozen or three benchmarks and need nanosecond-accurate timings of threaded code then switching to the full-blown Google Benchmark library should be considered. The benchmark framework is hard-coded to run each benchmark for one wall-clock second, and then spits out .csv-format timing information to stdout. It is left as an exercise for later (or maybe never) to add command-line arguments to specify which benchmark(s) to run, how long to run them for, how to format results, etc etc etc. Again, see the Google Benchmark framework for where that might end up. See src/bench/MilliSleep.cpp for a sanity-test benchmark that just benchmarks 'sleep 100 milliseconds.' To compile and run benchmarks: cd src; make bench Sample output: Benchmark,count,min,max,average Sleep100ms,10,0.101854,0.105059,0.103881 --- src/Makefile.am | 5 +++++ 1 file changed, 5 insertions(+) (limited to 'src/Makefile.am') diff --git a/src/Makefile.am b/src/Makefile.am index 67e848be39..45346df954 100644 --- a/src/Makefile.am +++ b/src/Makefile.am @@ -61,6 +61,7 @@ endif bin_PROGRAMS = TESTS = +BENCHMARKS = if BUILD_BITCOIND bin_PROGRAMS += bitcoind @@ -445,6 +446,10 @@ if ENABLE_TESTS include Makefile.test.include endif +if ENABLE_BENCH +include Makefile.bench.include +endif + if ENABLE_QT include Makefile.qt.include endif -- cgit v1.2.3
