New Issue was created.

Issue 386: https://gitlab.com/gnuwget/wget2/issues/386
Author:    Darshit Shah

The performance of the HTTP/2 client code seems to be absolutely terrible.

This part is in serious need of profiling.

I tested this by downloading a 10GB file from a remote server over a very fast 
ethernet connection, here are the results:

Wget 1.x:
Saving to: ‘/dev/null’

   9,31G  89,9MB/s    in 2m 13s  

2018-06-13 19:01:01 (71,7 MB/s) - ‘/dev/null’ saved [10000000000/10000000000]

Wget2 with HTTP/2:
/dev/null              1% [>                                                    
                                                                    ]  133.46M  
                          [Files: 0  Bytes: 0  [0 B/s] Redirects: 0  Todo: 1  
Errors: 1                                                             ]

Wget2 without HTTP/2:
/dev/null            100% 
    9.31G   89.73MB/s
                          [Files: 1  Bytes: 9.31G [88.86MB/s] Redirects: 0  
Todo: 0  Errors: 1                                                      ]

I had to kill the Wget2 with HTTP/2 process since it was too slow. But this 
really does show that the HTTP/2 code needs a lot of work.
