[jira] [Created] (TS-912) TSFetchURL slow
TSFetchURL slow
---------------
Key: TS-912
URL: https://issues.apache.org/jira/browse/TS-912
Project: Traffic Server
Issue Type: Bug
Components: TS API
Affects Versions: 3.0.0
Environment: Linux
Reporter: Naveen
Running a Apache benchmark with a simple plugin that just does TSFetchURL gives a ~13ms response time. The Fetch was on a localhost. All the plugin does is just sends an "hello world" response to the client.
http://pastebin.com/1uEvuZqk
Removing the TSFetchURL from the picture gives a response time of <1ms.

[jira] [Commented] (TS-912) TSFetchURL - poor performance
Posted by "James Peach (Commented) (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/TS-912?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13168707#comment-13168707 ]
James Peach commented on TS-912:
--------------------------------
I believe that this happens when the whole response is delivered in a single event handler invocation. In this case, read_from_net() delivers the read event, but not not notice that it read to EOF and so does not deliver the EOS event. The plugin has to wait for a TCP timeout to get the EOS delivered.
