Alexander Kuzmenkov	f514d0da77	Revert "Run perf tests with memory sampling (for allocations >1M)"	2020-07-07 19:59:42 +03:00
Azat Khuzhin	307c3c92a5	Run perf tests with memory sampling (for allocations >1M) ... This is to know the memory allocation size distribution, that can be obtained later from left-metric-log.tsv. This is an attempt to tune tcmalloc (new CPP version by google) to use lock-free part of the allocator for typical allocations (and it is a bad idea just to increase kMaxSize there, since number of allocation for each size class is also important). P.S. hope that this file will be applied, if no, then the same effect can be reached by tunning defaults in Settings.h Refs: #11590 Cc: @akuzm	2020-07-05 12:43:12 +03:00

Alexander Kuzmenkov	7ba5063b7a	Add concurrent benchmark to performance test ... After the main test, run queries from `website.xml` in parallel using `clickhouse-benchmark`. This can be useful to test the effects of concurrency on performance. Comparison test can miss some effects because it always runs queries sequentially, and many of them are even single-threaded.	2020-06-12 00:24:56 +03:00
