RE: performance of cgi-interactive programs -- WEB400

I guess the questions to ask you are:

What are you using to present the pages to the customers? Hand-written
HTML/CGI; CGIDEV2; WebFacing; Net.Data; Other?

If you have graphics on the webpage, that WILL slooow it down quite a
bit regardless of style used.
