[Zope] Response with a big file

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. -- Microsoft merges technologoies: Windows CE + Windows ME + Windows NT = Windows CEMENT ---- Antonio Beamud Montero Agora Systems S.A. http://www.agoratechnologies.com
