Depends on what you mean.  If you're talking desktop line-of-business software 
for the IRS, a bank, or any business then there's probably not going to be a lot 
of heavy math.  If you're talking some sort of automatic transaction processing 
then maybe different, but I can't see the math really being that hoary.  I've 
seen financial transaction software written in TCL which was running a *lot* 
slower than Python.  Even in that case, I/O for getting yuor transactions and 
storing your results are going to be over head so I would really discount Python 
  unless the example could be defined better.  I'd seriously consider Python to 
start with (but I'd consider Smalltalk first so..)

A browser is a fairly straightforward piece of work that I think any slowness in 
a particular language is going to be noticed when you repeat a fundamental 
operation (render an element) many, many times.  I think there's going to be a 
lot more 'stuff' going on in office suite.  That's just speculation, the real 
reason I didn't consider #2 was that I overlooked it

Take care,
Jay
