using reactivemongo ping sometimes is really slow

[br...@interpayments.com]

In some health-check scenarios, we execute a ping() operation.  Occasionally that ping takes 3 to 6 seconds (in general "slow") and there appears to be no reason for the latency.   When that happens there appears to be no transient network issues (a native scala driver "ping" is always fast), nor atlas monitoring abnormalities.  Not host machine resource constraints (cpu. memory, JVM).

Anyway,  just curious if there was a suggestion on what *might* be constraining the command request/response from being not-slow.   If there a debug level that might show what might be wrong?  are there suggestions on executioncontext configuration tweaks.  95% of the time, performance is just fine wrt all other operations and pings.

Thanks in advance.
