What could be reasons for my rsync, which is syncing two remote servers through ssh, to slow down over time like this? It keeps happening. How to check what is the bottleneck?

I've had some luck establishing the bottleneck using strace on both the sender side and receiver side. This will show if the sending rsync is waiting on local reads or remote writes and if the receiving rsync is waiting on network reads or local writes.
This helps find the specific resources to check.
