William Bardwell created TS-1320:
------------------------------------
Summary: Reading from SSL origin can starve sending data to client
Key: TS-1320
URL: https://issues.apache.org/jira/browse/TS-1320
Project: Traffic Server
Issue Type: Bug
Components: Network
Affects Versions: 3.0.4
Reporter: William Bardwell
Priority: Minor
When we had a fast connection doing SSL to an origin server, and a slower
connection to the client, and not very much CPU, the SSL VConn code would start
to spin reading data from the origin server, and not breaking out of the loop
at all to send data to the client. As a result the throughput to the client
would drop to zero and ATS would get a bit bigger. So my proposed patch is to
have the SSL VConn code not stay in its loop when it has some data that it has
read, this matches how non-SSL network VConn's work. My one concern with this
is that there might have been a good reason for that looping, and that this
might slow down cases when things are working properly.
