I recently read that TCP BBR has significantly increased throughput and reduced latency for connections on Google’s internal backbone networks and google.com and YouTube Web servers throughput by 4 percent on average globally - and by more than 14 percent in some countries. The TCP BBR patch needs to be applied to the Linux kernel. The first public release of BBR was here, in September 2016. The patch is available to any one to download and install. Another option is using Google Cloud Platform (GCP). GCP by default turned on to use a cutting-edge new congestion control algorithm named TCP BBR.

Thanks very much.
I’d come across this a few months ago but never went through with it at the time.
I finally took the plunge now and have gone from 80 Mbps to 89 Mbps (on a 100 Mbps link) based on the iperf test.
Clear and well written article with enough detail to satisfy my questions, thanks again.

Iperff 2 allows one to set BBR, reno, etc. using -Z. There are a lot of new features around speed or latency in 2.0.14
