Slow transfer rate

[vjyanand]

Trying to send a file from client to server using quinn . I see time taken to transfer files is 5x slower than scp. Here is code for Server and Client. Can you please help me identify issue in using the library. Sorry, if I ask, but I don't understand slowness with the code.

Thanks for the report! I had a look through your code and didn't see any obvious mistakes. Can you provide some details on your test environment? In particular:

• Debug or release build
• Theoretical link capacity on client/server
• Latency and packet loss on the path
• Exact speeds observed for scp and quinn
• Any observed variation in quinn speed over the course of a single large transfer
• What CPU the client/server have
• CPU load on client/server before and during transfer
• client/server OS

Quinn could definitely be faster (see e.g. #501) but we reliably hit >1Gbps on loopback tests, so depending on details it's possible there's something interesting going on here.
