The issue with Cfoutput is that it parses everything between the two tags looking for CF variables to output -including any HTML that might be between the tags. If you have a lot of HTML between your <cfoutput></cfoutput> tags, and just a few variables, you are making CF wade through a lot of code that it doesn't need to. However, the penalty in many cases is negligable and should be ignored in favor of the ease of use (don't you hate going through and bracketing every little thing in CF output tags?). In our own testing we have been unable to prove that <cfoutput> is slower than a comparable cfloop - but we do make an effort to make the HTML that is between a <Cfoutput query="yada"></cfoutput> tags reasonably lean.

I can't find the article for the life of me, but I think Michael Dinowitz or somebody wrote an article some time ago comparing the two methods. From what I remember CFLOOP is faster because it is a "dumbed down" way of outputting your data. It doesn't look for record set counts or anything, it just loops over whatever you give it. I wish I could support this claim with valid links to writings, but I know I have heard and read that CFLOOP is faster.
