This would be much more interesting if you had any idea about what you are
talking about.  A disk I/O takes about 5ms.  20 egtb probes in a search will
burn 1/10th of a second.  200 probes will burn a second.  That is _not_
instantaneous.  For a program searching 2M nodes per second, the speed can slow
down to 20,000 nodes per second easily given the right position.
