LWN.net Weekly Edition for June 13, 2013
A report from pgCon 2013
Little things that matter in language design
in many cases they are not where you expect them to be (the hyperthreaded cpu utilisation is one example, locking overhead with multiple processors is another)
frequently there are factors in play that you don't know about, and the result is that until you test it to a particular load, you have no way of knowing if the system will reach that load.
interpolation (guessing how things work between measured points) is fairly reliable
extrapolation (guessing how things will work beyond measured points) is only reliable until some new factor shows up.
