I'm sure you will.  In fact, I'm pretty sure that it could be sped up  
by optimizing some of the Python code.  For our largish databases, the  
old pack typically used a small percentage of the CPU most of the  
time, whereas the new packing code is mostly CPU bound, because it  
does much saner I/O.
