Switched from using timestamps to RTT estimates when performing TCP receive buffer auto resizing, as not all hosts support / enable TCP timestamps.
Disabled reset of receive buffer auto scaling when not in bulk receive mode, which gives an extra 20% performance increase.
Also extracted auto resizing to a common method shared between standard and fastpath modules.
With this AWS S3 downloads at ~17ms latency on a 1Gbps connection jump from ~3MB/s to ~100MB/s using the default settings.
