Class::DBI currently breaks the transaction-safety feature of
Apache::DBI.  This is not an issue if you are using MySQL without
transactions.  See this message for more:

I can't give you a ballpark, but you should expect some jump.  The
amount really depends on how you use it.  If you load large sets of data
as Class::DBI objects, it will be significantly larger than doing the
same thing with basic DBI results.  If you only work with small sets
loaded at once, your main increase will just be form additional modules
being loaded.  Load your Class::DBI stuff in startup.pl to minimize the
unshared memory.
