> currenty, http2 client use all http1.1 settings, that cause http2 client 
> performance is so bad.
>  
> we need to conside http2 client settings at least:
> 1.concurrent stream in one connection, default value is 3, we must make it 
> bigger
> 2.maxPoolSize, http1.1 need a big pool, but http2 need a big concurrent 
> stream count
>  
> we must perform a performance test, that make sure got a good result, and 
> then set the setting to be our default setting.
