[Zope] Large XML files

I am testing the possibilities of delivering the content of XML Documents through the Zope environment. Unfortunately, some of the proposed file are rather large (up to 760KB) and just uploading them and viewing them on our current Zope server is prohibitively slow. Our server, running Z2 is a blazing P133 running NT 4.0 with 32 MB of RAM (I get the bottom feeders). Is the bottleneck the hardware; is there something I can do software-wise to improve performance; or is development not yet advanced enough to handle this scenario efficiently? Any opinions on this? Thanks, P. Johnson
