Yeah, it's more of a safeguard to ensure one avoids those types of issues.
As for your current situation, I did have a customer the other day who
was reporting multi-hour replication delays. But when I looked into it,
the issue was not unexpected. I don't know if this has any relevance to
your situation, but here is what they were doing.
They had a 4-way MMR setup. They were doing 50k ADDs to each of the
masters. This is one of the worst things one could do, becuase it will
massively slow down replication and cause all the servers to get behind
due to the contention caused by the massive number of ADD ops occurring
on each server while also trying to replicate the ADDs from the other
servers. I.e., the best route would be to simply ADD all 150k entries to
a single member node and let them replicate out from there.
