Getting a handle on Python's execution speed is not easy.  The problem 
is that the core library is mostly written in C, so operations that 
happen inside the core library are fast.  Operations that happen in 
user-written Python code are slow.  How fast your overall program will 
run is largely determined by how much you're executing user code and how 
much you're executing library calls.

People have done lots of comparisons of language execution speed over 
the years.  If you google for "python speed comparison", you'll find 
plenty of more detailed answers than you'll get here.

Yes, they can.  However, CGI is largely an obsolete interface, partly 
because it's so inefficient.  If you're worried about execution speed, 
CGI is not what you should be looking at.

Yes.  There are a number of modules out there for doing this.  Again, 
google is your friend.  Search for "python charting module", or 
variations on that.
