improve server->client tcp performance for high latency links 

similar to the other fix, if we do not set the buffer size manually,
we get better performance for high latency connections

restore benchmark from f.gruenbicher:

no delay, without patch: ~50MB/s
no delay, with patch: ~50MB/s
25ms delay, without patch: ~11MB/s
25ms delay, with path: ~50MB/s

my own restore benchmark:

no delay, without patch: ~1.5GiB/s
no delay, with patch: ~1.5GiB/s
25ms delay, without patch: 30MiB/s
25ms delay, with patch: ~950MiB/s

for some more details about those benchmarks see
