Hi

Possibly a question that would fit better in a Linux net dev forum but anyway..

I have one short question. Is slow start after idle generally disabled (net.ipv4.tcp_slow_start_after_idle=0) for instance  for HTTP video streaming ?.

I can imagine that there are some benefits with avoiding the CWND decrease in idle periods.
Of course there is a problem that a large amount of data is transmitted when new objects are sent to the TCP sockets (shown on page 12 in https://www.ietf.org/proceedings/96/slides/slides-96-iccrg-1.pdf ), but packet pacing can solve this issue.
