Zope hasnt done that since version 2.... today the File object passes data to 
ZServer as fast as it can, using RESPONSE.write, and ZServer spools the file 
to a temp file. This frees up the thread and ZODB connection as soon as 
possible. ZServer then trickles data from the temp file back to the client 
using the medusa thread.

I guess the bottleneck comes from thrashing the temp file. If so, it would 
help to have a new mechanism allowing ZPublisher to go direct to the ZODB 
storage.
