I have to take issue with your last paragraph. I don't know what's going on in the examples in the book because I don't own it. However, as has been discussed here way too many times (check the archives), CFLOOP QUERY="" has been tuned starting with CF 4.01 to be faster than CFOUTPUT QUERY="". Now, there are many variables that play into making that statement (query size, etc.), but the general "rule" has been that CFLOOP QUERY="" is a bit faster in the latest versions of CF. But I do want to point out that what Dave Watts said in a response to this thread is very true as well, and more important. There are lots of other areas (caching, etc.) to focus on first before looking at the performance difference between CFOUTPUT QUERY="" and CFLOOP QUERY="". Tackling those issues will lead to far greater performance statistics than whether you use CFOUTPUT or CFLOOP. Just my $.02.
