Hi Mario,

If you have no dependences between the different files that you're
processing, then in principle Soot shouldn't need to create Jimple for
the files that it's not updating, which would save you some time.  How
closely linked are your different classes?  How many classes are
application classes vs. library classes?

Note that Soot can read Jimple files, but that this doesn't seem to have
saved us any time.
