I totally agree with the concern, but the only way for a clean comparison here would be for me to spin up a new VM. I observe the exact same patterns as I get from the windows VM on our Linux 2.x prod box so assume they are the same.
There were a slew of TCP changes leading up to the 3 branch which included changing the default congestion control algorithm to cubic.
slow start after idle does not really play part here. The test is for a clean/new connection.
I am no expert but it is possible I could lower my IW on my 3.2 box to 3 to demonstrate the same pattern, however that too is not a clean comparison.
If my sys admins push me I may set up another VM to demonstrate this.
- snissn 15y agoThanks again for your blog post and comments in this thread! Experiments where you already are really confident about the conclusions are pretty silly, but I feel like despite that being skeptical in general to posts on the internet has value. I haven't investigated yet, but if I do investigate clear benefits of slow start and can make a corroborating case, i'll be happy to correspond and write it up in a blog post.. No promises though :)
