I can confirm that changing the HTTP client to curl does fix the issue. I can see much bigger buffers used in this case.
This answers my question however I would say Akka-Http still should be guarded from such case (i.e. never emit such small buffers, due to profound performance degradation, no matter how client is sending the data). Thank you so much for you help!
