Just to clarify further: it depends on the OS. WIndows OS is always

It depends on the speed of the chips, of course (and unfortunately,
we're not very well threaded at startup because of the classloader and
other issues, so the extra core doesn't help). But it's maybe 5-8
seconds on current hardware.
