This isn't a VPN problem, it's just the nature of the internet. In practical terms, the farther away a server is from you, the more likely it is you'll have poor latency and lose data packets. In English, the more slowdowns and data loss there is in a connection, the slower the connection will go.

TCP, the internet's fundamental network protocol, overall throughput is inversely proportional to latency and packet loss. Similar techniques were applied by other VPN protocols. That's a good start, but to further improve it, since by itself this doesn't properly load-balance OpenVPN processes, other code changes make sure the OpenVPN load is properly distributed between the multiple processes. For example, to give the popular OpenVPN and other single-threaded protocols a kick in the pants, ProtonVPN has re-written OpenVPN so that multiple OpenVPN processes per server now run to take advantage of multi-core processors.
