[jira] [Created] (TS-4324) Inefficient way of transferring data frames

Bryan Call created TS-4324:
------------------------------

             Summary: Inefficient way of transferring data frames
                 Key: TS-4324
                 URL: https://issues.apache.org/jira/browse/TS-4324
             Project: Traffic Server
          Issue Type: Improvement
          Components: HTTP/2
            Reporter: Bryan Call


ATS transfers data 8K - 9 bytes (http/2 header size) and then sends the 9 bytes is couldn't write in a new frame that only has 9 bytes.  This also happens if you bump up the buffer size to 16K.

{code}
[  1.036] recv DATA frame <length=8183, flags=0x00, stream_id=13>
[  1.036] recv DATA frame <length=9, flags=0x00, stream_id=13>
[  1.259] recv DATA frame <length=8183, flags=0x00, stream_id=13>
[  1.259] recv DATA frame <length=9, flags=0x00, stream_id=13>
[  1.259] recv DATA frame <length=8183, flags=0x00, stream_id=13>
[  1.259] recv DATA frame <length=9, flags=0x00, stream_id=13>
