Thanks for the clarifications. For the slow link path, we don't have much option as the data transfer happens over the internet. I was trying to figure out the ways to reduce the gap as less as possible, for which I have read somewhere that we should have a sufficient value for max_wal_sender, and I was thinking that I can increase the data transfer happening by increasing the wal senders to gain some advantage. That is why, I asked that question. Thanks again.
