[Zope] Response with a big file

[Antonio Beamud Montero]

Hello all:
I have a problem when I try to return a big file (a multimedia file
exactly) in a response, i.e. a user request for a file, the a I generate
this file and return him with the minimal headers (like content-type,
Content-disposition...)... then zope starts to eat CPU time (99%) and
spends a lot of time in start to send this response...

What can be the problem? 
I have apache in front of zope 2.5.0.

A lot of thanks.
