Subject [jira] Commented: (CHUKWA-392) fair queuing for threads in collector
Date Mon, 21 Sep 2009 20:35:15 GMT

    [ https://issues.apache.org/jira/browse/CHUKWA-392?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12758018#action_12758018

Ari Rabkin commented on CHUKWA-392:
-----------------------------------

At higher data rates per node, this patch is actually a big win. I'm seeing drastic reduction
in retransmits, and a consequent big improvement in goodput.

> Right now, we don't write data in order received. This means that backpressure doesn't
work right.
