It will also be helpful if you can share how you emulate the latency and loss.
I tried the same thing. Slightly higher RTT I think since I added the extra 40ms on top of a 13-15ms actual latency. Anyway, 6 minutes later, only 2xx MB...
By the way between the same two hosts I use, iperf3 with a forced 1280 MSS gives me 183-202 Mbit/s (Without forcing MSS to be as small as what we...
You can also try to see if GSO helps on your host. For me it didn't. The param is -quic_bathing_mode=1.
We don't have good PMTUD support at this moment. If you happen to know a proper MSS size that can work well in your network, we can add a param...
hey @Enjia can you try with the a few params i mentioned and let me know if it helps? Thank you!
When you keep increasing MSS, at certain point it will be beyond your network's MTU and packets will be dropped, thus the timeout error you saw. Currently we don't have...
@Enjia Just another quick question, what's the linux kernel version on your testing machines? UDP GSO was added in 4.18 iirc. By the way there is no benefit of tuning...
Looks like connection closed due to PTO limit when transfer 5GB file is not related to the transport: https://github.com/facebook/proxygen/issues/307
I don't have the number but i believe there is small fraction of out of order in our network. Yes sendmsg is where we spend lots of CPU. For the...
