Andrey Gura commented on IGNITE-4587:
-------------------------------------
[~dreamx], thank you very much for your contribution. But performance tests
showed performance drop for some configuration, so {{CLOCK}} mode is still
preferable for some cases.
It's possible that your PR will be useful in the future.
Thanks a lot again :)
