Subject: [Bloat] Progress with latency-under-load tool
Date: Wed, 16 Mar 2011 04:31:44 +0200	[thread overview]
Message-ID: <0D59AD34-AA64-4376-BB8E-58C5D378F488@gmail.com> (raw)

I'm finally getting a handle on sockets programming again - the API has actually *changed* since I last used it - so the testing tool I was talking about is starting to actually do semi-useful things.

For example, just over the localhost "connection", maxRTT is already almost 2ms with no load.  That's CPU scheduling latency.  The tool prints this out as "Link Responsiveness: 556", since it displays Hz in order to give marketing-friendly "bigger is better" numbers.

Now to write a couple of lovely functions called "spew" and "chug".  I'll let you guess what they do...

 - Jonathan
