How long does it take to make a context switch? (2010)
Pretty sure that he&#x27;s just rediscovering what I did in lmbench back in the early 1990&#x27;s.  All written up and open source (and got best paper in the 1995 Usenix):<p><a href="http:&#x2F;&#x2F;mcvoy.com&#x2F;lm&#x2F;bitmover&#x2F;lmbench&#x2F;lmbench-usenix.pdf" rel="nofollow">http:&#x2F;&#x2F;mcvoy.com&#x2F;lm&#x2F;bitmover&#x2F;lmbench&#x2F;lmbench-usenix.pdf</a><p>Edit: which now that I think about it, was over 20 years ago.  Reminds me of something a friend (Ron Minnich) said long ago: people rediscover stuff in computer science over and over, nobody wants to read old papers.  Or something like that.  He said it better, I think it was something like &quot;want to look smart?  Just take any 5 year old paper and redo whatever it did, our attention span seems to be very short.&quot;
