That is a 50% speedup compared to 2.0 :)  If we consider its speed as
being how many times you could do this per second, then 2.0 speed is
1/2.72, and 2.2.1 speed is 1/1.82.  Speed ratio is then
2.72/1.82=1.4945.  So 2.2.1 is 1.5x the speed of 2.0, or 50% faster :)

Andy, who is not looking for praise, but who likes perf numbers :)
