hi i'm a parrot from zope-dev:

in addition to chrisw's comments.

if any of these classes are by change catalog aware, thats probably your 
answer, since your doing incremental updates to the catalog for each add call.

if they are catalog aware, you're better off using a non-catalog aware class, 
and doing a batch catalog on them when you're done adding.

die parrot, die.

another option is try and store them in an intermediate format on the server, 
and then load them up all at once via an external method.
