Dubbo provider will try to generate and return the Response for every RPC call it receives, even for those timeouted calls.

Look at the code on the consumer side, for the timeouted request, it does nothing but prints a warning log, actually, maybe that is the only thing the consumer can do for a timeouted request.

So my suggestion here is think of a way to stop the provider from sending responses for timeouted requests, discarding those requests directly on provider side.
