Not having any experience with this domain, I can't comment on this.

Being "interpreted" is a quality of an implementation, not of a 
language. And the reference implementation of Python (CPython) is not 
interpreted, it's compiled to byte-code, which is then executed by a VM 
(just like Java). So while CPython may possibly be too slow for your 
application (it can indeed be somewhat slow for some tasks), the reasons 
are elsewhere (hint: how can a compiler safely optimize anything in a 
language so dynamic that even the class of an object can be changed at 
runtime ?) ...
