I know when one of our guys decided to take a complex series of included files and put it into 4 CFCs to make things easier to manage that the pages actually slowed down. When he started to back track through things it appeared the added overhead was from all of the method calls he was then making.
A couple years ago I inherited a process that would bring a CF server down to its knees when it would run due to what appeared being an issue with CF never releasing resources after they were used until the page itself quit running. At the time the work around and it was not a pretty one was to send the processing to another page, so that it was another page call but in order for that to work on that version of CF at least it meant calling a web service within the same application. Our internal reservation system originally had a 5000 line CFC that it used for the bulk of things. Not sure how many methods were in it, I doubt anywhere near 100 but I also know in most cases only 2-3 methods were ever used. When we split things out into 6 CFCs we saw no performance hit either way.
