This smells a bit like an XY problem (see
<http://www.perlmonks.org/index.pl?node_id=542341>), and I can't
immediately see what Fcntl has to do with pipes, named or otherwise. It
might help if we had more information about what you are trying to
accomplish. In any event, you might want to consider other IPC
mechanisms before pipes, like shared memory or sockets.

Also, bear in mind that if you are not using mod_perl, your CGI script,
and the Perl interpreter, will be read from disk for every request.
Unless reading that data file is time consuming for some reason (e.g. it
is huge, or remote), speeding it up may not improve the response time
for your HTTP request by very much.
