The answer is... it all depends. FTP uses an extra control connection,
plus one connection per file - however, it only forks once per session.
HTTP forks once per request, so it should use more CPU there. 

The problem may well be down to the particular implementation of HTTP/FTP.
NCSA httpds have the well known problem when reading HTTP/1.0 headers that
raise the CPU  requirements. Both CERN and NCSA are cpu limited for a 
10Mbps ethernet and 4K requests
