I would like to know the speed difference between running a solution on the old a new systems.
In the past, I liked to make a code that runs in less than 2 seconds (as this was the real time limit intended by the most of the problem authors). In the new system, what should be equivalent to 2 seconds in the old one? Is it something like 0.3 second?

I think it is hard to say. I've gotten code that runs at least 3 times as fast on the new system. I also noticed that STL runs faster on the new judge.
