Having looked at a number of reports, and optimized some by factors of 
5 or more, I don't think changing the language will help this problem. 
Even if the Guile interpreter were infinitely fast, some reports would 
still be slow because of the algorithms they use.  They often do 
multiple passes over large searches through the Gnucash data.  That is 
where the time often goes.  Of course if all the reports were 
rewritten, these problems might be fixed in passing.
