Your Feature Request

When we tested using the QUIC protocol to upload files, we found that the QUIC protocol transmission parameterinitial_max_data set by haproxy was equal totune.bufsize, while the default value oftune.bufsize was only 16KB, resulting in frequent transmission of MAX-STEAM-DATA frames (for flow control) when uploading files using the QUIC protocol, leading to extremely low bandwidth utilization.
After setting the tune.bufsize to 1MB, the number of MAX-STEAM-DATA frames decreased significantly and the upload speed improved significantly, but this resulted in an increase in resource consumption for TCP/HTTP requests.
Is there a configuration that can separately set the initial max_data of the QUIC protocol without affecting other requests.

What are you trying to do?

I hope there is a separate configuration option to setinitial_max_data for QUIC protocol instead of usingtune.bufsize.
