Hi,

I did an experiment:

1. Download “Network Link Conditioner” for mac. In this software, choose network to "Very bad" which is 10% loss package and 500ms delay.
2. Android Device connect mac's wifi.
3. In my app code:

enable http2 then send 100 same requests, and it fail 20+ times

4. disable http2 then send 100 same requests, and it fail about 5 times

This result is no accident, because i tried for many times.

Before I thought http2 is better than http1.1 ,especially when network is bad. But the truth is not.

So why is this happening? Is there some bug with okhttp's http2?

Thank u very much.

The takeaway here could be to make concurrency of a single stream tunable or controllable. Also maybe applies to sharing Video and critical API calls over the same connection, especially with coalescing.
