Subject: Re: [PATCH 2/2] vhost-net: add a spin_threshold parameter
Date: Mon, 20 Feb 2012 17:35:31 -0800 [thread overview]
Message-ID: <1329788131.13141.14.camel@localhost.localdomain> (raw)

We tried similar approach before by using a minimum timer for handle_tx
to stay in the loop to accumulate more packets before enabling the guest
notification. It did have better TCP_RRs, UDP_RRs results. However, we
think this is just a debug patch. We really need to understand why
handle_tx can't see more packets to process for multiple instances
request/response type of workload first. Spinning in this loop is not a
good solution.
Thanks
Shirley
