 There no facts auto-tuning is enabled at any settings for your case, with
 default buffer size (assume 8k) speed is 50KiB/s while with modified
 (256k) speed is 400 KiB/s.

 256k by default for recv and send will make popular windows relays to use
 more memory than linux relays, it's way for new ticket "Windows relay is
 several times more hungry than Linux relay".
