Charlie, I read your blog entry back in Jan and I couldn't help thinking that you wrote that with me in mind after our conversation about testing CFMX vs BD.net when I found that CFMX was faster using a specific piece of test code that I wrote.

It's not clear, as you say, what the 10-fold difference would really mean for a single switch on a single page (versus one appearing in a query loop, as the WebApper guys were noting). Indeed, people have long tried to "prove" the value of a tweak by putting it in a simulated large loop. I've made the argument that that's a fallacy: if the code doesn't really exist in a large loop, then it's not at all the same to conclude that such a simulated large loop test would equate to the performance improvement one would see if instead you ran a load test requesting the page a large number of times (but executing the tweaked only once). It's a point of some contention, and I blogged about it back in January: http://bluedragon.blog-city.com/fallacy_of_loop_testing.htm /charlie http://www.carehart.org/blog/ -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Adam Cameron Sent: Tuesday, August 08, 2006 6:19 AM To: Coldfusion Development Subject: RE: [cfug-lists] RE: [CF-Dev] CFSwitch...

This one? http://www.webapper.net/index.cfm?fuseaction=Fuseblog.showcomments&Artic leID=20060727042244 That's the only link I can see on posts from you (looking @ the archive... I don't keep the email messages). I don't see any metrics there. They say "10-fold difference". If the ten-fold difference is the difference between 0.05ms and 0.5ms... *who cares*? We're not going to be talking about the difference between 100ms and 1sec here. It's an interesting theoretical exercise, certainly. I'm yet to be convinced it has any practical important at all though. (needless to say, whilst sceptical, I'm not saying empirically "it doesn't matter", I'm simply suggesting "it might not really matter, in the bigger scheme of things"). -- Adam _______________________________________________ For details on ALL mailing lists and for joining or leaving lists, go to http://list.cfdeveloper.co.uk/mailman/listinfo -- CFDeveloper Sponsors:- >- Hosting provided by www.cfmxhosting.co.uk -< >- Forum provided by www.fusetalk.com -< >- DHTML Menus provided by www.APYCOM.com -< >- Lists hosted by www.Gradwell.com -< >- CFdeveloper is run by Russ Michaels, feel free to volunteer your help >-< _______________________________________________ For details on ALL mailing lists and for joining or leaving lists, go to http://list.cfdeveloper.co.uk/mailman/listinfo -- CFDeveloper Sponsors:- >- Hosting provided by www.cfmxhosting.co.uk -< >- Forum provided by www.fusetalk.com -< >- DHTML Menus provided by www.APYCOM.com -< >- Lists hosted by www.Gradwell.com -< >- CFdeveloper is run by Russ Michaels, feel free to volunteer your help -<
