On: Boosting upload speed and improving Windows' TCP stack

Are equivalents to linux' BQL/AQL, fq_codel, TCP_NOTSENT_LOWAT in the pipeline?

I cannot comment on queuing disciplines and limits in future products. Re. TCP_NOTSENT_LOWAT, you may want to look at the Ideal Send Backlog API that allows an application to have just more than BDP queued to keep the performance at the maximum throughput while minimizing the amount of data queued: https://docs.microsoft.com/en-us/windows/win32/winsock/sio-i...

Interesting. ISB does seem less ergonomic for blocking IO but it makes sense for overlapped requests.
