Translation: In our experience, large databases with a lot of objects  
can lead to very slow operations, such as packing and backing up the  
data. This might be improved by using a file  system designed for  
many small files, but on ext3 the whole thing became a terrible dog.  
This slowness also appears when doing automated buildouts which  
create lots of objects. Even simple stuff like just instantiating a  
Plone portal from the ZMI was noticeably slower.
