   Been there, done that.  I really doubt that any Python apps are doing   
   the level of what I do.  I would be careful telling people that Python   
   apps run anywhere near the speed of C++.   
      
   I used to have my data storage code written in Smalltalk, an interpreter   
   using automatic garbage collection.  It was about a 100X slower than my   
   C++ code.  Python is faster than the old Smalltalk language but not the   
   speed of C++.
