Users have reported use cases like MC servers, rdp #171 #209 for rathole. These interactive applications greatly benefit from the TCP_NODELAY flag, which is by default off. Considering large files transferring and web disk application usage for rathole is relatively rare. And even with TCP_NODELAY, rathole provides good bandwidth utilization. It will be reasonable to enable TCP_NODELAY by default.
Users who host web disk applications can still opt out TCP_NODELAY by configuration.
