And shaken bits don't convolve very well (in > extreme cases they can spill from one fft bin to the next!). Fact. You are both very right about this. Gold-plating the cpu socket will do wonders for the light and fast bits used to convolve the first few kilosamples of a long IR - being light (and thus having little kinetic energy) they really need low-resistance paths. For the later parts of the IR jconv uses heavy bits, and a lot of them. Having all this mass vibrate can put excessive stress on you CPU.
