Avi Kivity	b18e54307f	tests: add --operations-per-shard option to perf_simple_query ... This helps achieve more repeatable runs that can then be compared via the Linux perf tool. The option overrides duration-based testing and runs the test for a specific number of iterations. Message-Id: <20170204172937.8462-1-avi@scylladb.com>	2017-02-06 12:08:04 +01:00

Pekka Enberg	38a54df863	Fix pre-ScyllaDB copyright statements ... People keep tripping over the old copyrights and copy-pasting them to new files. Search and replace "Cloudius Systems" with "ScyllaDB". Message-Id: <1460013664-25966-1-git-send-email-penberg@scylladb.com>	2016-04-08 08:12:47 +03:00
Vlad Zolotarov	0f8090d6c7	tests: use steady_clock where monotinic clock is required ... Use steady_clock instead of high_resolution_clock where monotonic clock is required. high_resolution_clock is essentially a system_clock (Wall Clock) therefore may not to be assumed monotonic since Wall Clock may move backwards due to time/date adjustments.

Tomasz Grabiec	d21966ecbc	Revert "tests: Use lowres_clock in time_it()" ... This reverts commit e605a0368a. lowres_clock is not updated when reactor is not running and this variant of time_it() is not meant to be run in a rector.	2015-03-30 18:38:26 +02:00

Pekka Enberg	a3b2a70f65	tests/perf: CQL statement parser performance test ... Add a performance test case for CQL statement parsing to better understand its performance impact. We also include ANTLR tokenizer and parser setup as that's what we do in query_processor for each request. Running the test on my Haswell machine yields the following results: [penberg@nero urchin]$ build/release/tests/perf/perf_cql_parser Timing CQL statement parsing... 108090.10 tps 125366.11 tps 124400.64 tps 124274.75 tps 124850.85 tps That means that CQL parsing alone sets an upper limit of 120k requests per second for Urchin for a single core.

Tomasz Grabiec	543cc40d1a	tests: Add performance test for in-memory row mutation ... It shows that our serialization code, which is using ostringstream under the hood, is really dragging us down.
