Summary: This diff allow us to run a single benchmark X times and warm it up for Y times. and see the AVG & MEDIAN throughput of these X runs for example ``` $ ./db_bench --benchmarks="fillseq,readseq[X5-W2]" Initializing RocksDB Options from the specified file Initializing RocksDB Options from command-line flags RocksDB: version 4.12 Date: Wed Aug 24 10:45:26 2016 CPU: 32 * Intel(R) Xeon(R) CPU E5-2660 0 @ 2.20GHz CPUCache: 20480 KB Keys: 16 bytes each Values: 100 bytes each (50 bytes after compression) Entries: 1000000 Prefix: 0 bytes Keys per prefix: 0 RawSize: 110.6 MB (estimated) FileSize: 62.9 MB (estimated) Write rate: 0 bytes/second Compression: Snappy Memtablerep: skip_list Perf Level: 1 WARNING: Assertions are enabled; benchmarks unnecessarily slow ------------------------------------------------ Initializing RocksDB Options from the specified file Initializing RocksDB Options from command-line flags DB path: [/tmp/rocksdbtest-8616/dbbench] fillseq : 4.695 micros/op 212971 ops/sec; 23.6 MB/s DB path: [/tmp/rocksdbtest-8616/dbbench] Warming up benchmark by running 2 times readseq : 0.214 micros/op 4677005 ops/sec; 517.4 MB/s readseq : 0.212 micros/op 4706834 ops/sec; 520.7 MB/s Running benchmark for 5 times readseq : 0.218 micros/op 4588187 ops/sec; 507.6 MB/s readseq : 0.208 micros/op 4816538 ops/sec; 532.8 MB/s readseq : 0.213 micros/op 4685376 ops/sec; 518.3 MB/s readseq : 0.214 micros/op 4676787 ops/sec; 517.4 MB/s readseq : 0.217 micros/op 4618532 ops/sec; 510.9 MB/s readseq [AVG 5 runs] : 4677084 ops/sec; 517.4 MB/sec readseq [MEDIAN 5 runs] : 4676787 ops/sec; 517.4 MB/sec ``` Test Plan: run db_bench Reviewers: sdong, andrewkr, yhchiang Reviewed By: yhchiang Subscribers: andrewkr, dhruba Differential Revision: https://reviews.facebook.net/D62235 |
