For Mode BSGS that use RAM to store precalcualted data you can reach some Petakeys/s scanning for a single publickey.
... though BSGS speed is not comparable to the standard scanning technique. Just for the sake of correctness, you cannot compare apple speed with pie speed displayed by those tools. I only want to mention this so that no false illusion is created in the reader and he might think that BSGS is the means of choice and thus the holy grail.
