How slow it is compared to C/C++ is based on what you are doing with it. For 
somethings it is within 10-20% and sometimes less it just depends where your 
app is spending most of its time. 10-1000 times slower although if yours is 
100-1000 times slower then your program probably has an error as has been 
demonstrated on another thread here recently on speeding up an image app buy 
using different data structures. 

For my own uses python is more then fast enough but my apps are also mostly io 
and network bound not cpu bound.
