Database Size Vs System Performance

How does the number of objects(PFs & LFs) that DB2 has to "maintain" affect
system performance?

Right now, Production library sits at 42GB with 175 PFs and 375 LFs.  We also
currently have a Test library with the same objects, but only a subset of data.
 We want to add a Development Library and a Training Library.  So the number of
file objects on the system would double.  The data in the Test library will also
become a complete copy of production data.  The other two will remain at being
only a subset of data.

Thanks,
   Scott
