@amosbird could you please add perf test from linked issue ? |
|
@kitaisreal There is already a test https://github.com/ClickHouse/ClickHouse/blob/master/tests/performance/modulo.xml for this. Maybe the difference is not evident. |
There was an obvious difference but somehow the test was not marked as failed. I'll investigate. |
