Amelchev Nikita commented on IGNITE-15666:
------------------------------------------

[~slava.koptilin], I think this metric should not be used to calculate the 
average time. We can have several backups, unstable topology, clients reconnect 
etc that will lead to a wrong value. (in addition, batch remove time also count 
missed removals but by the JCache API specification should not)

I think we should implement a correct time metric for that purpose. 

> The remove metric value is different for sync and async methods
