This depends, it can go from 15-20 minutes to over 4 hours.I think you just pointed to the local technology press being negligent to a degree never before seen. This is the first I have heared about such a thing (these things usually make it all the way into the mainstream press).
A company in Israel has built a 8000 Ghz (Not a typo, it's Ghz) processor, that
may take it down to a few seconds.
Do you know the company's name?
