Efficiency of FTP URLs

Greetings,
We have been having a small, local discussion on the efficiency of
FTP vs. HTTP. One of the items I pointed out was that for serving up an HTML
document with inlined images, FTP is very inefficient because of the startup
costs for every inlined images. Later I got to thinking that this would be
an obvious place for an optimization: leave the FTP open until done parsing
the HTML document in case any inlined images (or whatever) might be needed.
This morning I confirmed that MacWeb 1.0a2, MacMosaic 2.0a2, XMosaic
2.4, and WinMosaic 2.0a2 take the inefficient approach of a separate ftp
connection for each inlined image. It would seem that optimizing this would
help the load on ftp servers, and response time to the user.
