Review comment:
My goal for this ticket was to see timings in the logs and have ability
to compare with another ignite versions. Timings appear strange. But test works
as it can with current bug in discovery and the disadvantages with multiple IP
addresses. Test show timings but was not supposed to do assertions. Is it
another ticket?
