Alan Paxton 6781009ee8 CI Benchmarking. Small configuration changes based on performance analysis. (#11074) ... Summary: First, we made a small reduction in DURATION_RW as runs were exceeding 1 hour and colliding with subsequent runs. See Mark Callaghan’s blog post at http://smalldatum.blogspot.com/2023/01/variance-in-rocksdb-benchmarks-on-cloud.html Configuration parameters which are not consistent with the following email from Mark (see the blog post for more context) have been updated. Where Mark has defined the parameter and we haven't, we define it explicitly. We will need to further monitor for an expected reduction in variance of test times: To match what I did: --- nsecs=1800 dbdir=/data/m/rx resultdir=bm.lc.nt1.cm1.d0 env WRITE_BUFFER_SIZE_MB=16 TARGET_FILE_SIZE_BASE_MB=16 MAX_BYTES_FOR_LEVEL_BASE_MB=64 MAX_BACKGROUND_JOBS=4 NUM_KEYS=20000000 CACHE_SIZE_MB=10240 DURATION_RW=$nsecs DURATION_RO=$nsecs MB_WRITE_PER_SEC=2 NUM_THREADS=1 COMPRESSION_TYPE=none CACHE_INDEX_AND_FILTER_BLOCKS=1 VALUE_SIZE=400 NUMA=1 MIN_LEVEL_TO_COMPRESS=3 COMPACTION_STYLE=leveled bash benchmark_compare.sh $dbdir $resultdir 7.8.fb env WRITE_BUFFER_SIZE_MB=16 TARGET_FILE_SIZE_BASE_MB=16 MAX_BYTES_FOR_LEVEL_BASE_MB=64 MAX_BACKGROUND_JOBS=4 NUM_KEYS=200000000 CACHE_SIZE_MB=10240 DURATION_RW=$nsecs DURATION_RO=$nsecs MB_WRITE_PER_SEC=2 NUM_THREADS=1 COMPRESSION_TYPE=lz4 CACHE_INDEX_AND_FILTER_BLOCKS=1 VALUE_SIZE=400 NUMA=1 MIN_LEVEL_TO_COMPRESS=3 COMPACTION_STYLE=leveled bash benchmark_compare.sh $dbdir $resultdir 7.8.fb Pull Request resolved: https://github.com/facebook/rocksdb/pull/11074 Reviewed By: ajkr Differential Revision: D42969668 Pulled By: cbi42 fbshipit-source-id: 1ea4e6a3901be4016108f93817eb58f74baac21a		2 years ago
