Revert "Run perf tests with memory sampling (for allocations >1M)"
2020-07-07 19:59:42 +03:00

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

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.
