Alexey Scherbakov commented on IGNITE-24118:
--------------------------------------------
> The difference is about 7-8K operation, but the deviation is about 30K.
The difference is bigger after merging changes for IGNITE-23304.
Switch to the ignite-23304 branch and compare two revisions:
638d15edab34b5b7004fb6aab062d1605b250c42 (before merging the main)
29cb8fa5a7042d015d836713bcf8b1589eb0be31 (head)
My results:
