Since you have given minimal information in this post, I doubt there is
really a way to compare to other situations. Collect the details you
provided earlier in the thread for those folks getting to it just now.
That would be:
1) Postgres versions on both ends
2) OS and versions on both ends.
3) Network distance between 'machines'.
4) The logical replication settings.

Since you have already started is that not already to late for this?
