My bad. Sorry. I will keep this discussion off list now. I hope I get the point across to the folks here that CFLOCK is a necessity rather than an option.

Why do people always feel they have to wage these wars in front of the list, when a post one-on-one off-list post would suffice? I suppose integrity, professionalism, and respect of the community aren't that important. --- Billy Cravens -----Original Message----- From: James Ang [mailto:[EMAIL PROTECTED]] Sent: Friday, June 14, 2002 4:19 PM To: CF-Talk Subject: RE: RE: Application Slow Down was RE: Absolutely necessary to cflock session variables "Try this formula: simple statement + irrelevent speculation = random idiocy" Ouch! :) I am assuming: Simple Statement == "Single Thread" the server Irrelevant Speculation == "CFLOCK is mucho importante!" Random Idiocy == James' dumbo statements Well, I am not sure what you have learned in your 20+ years of computing, but I am guessing you don't code for multi-user environments that much. I am sure you have heard of the need for semaphores (aka mutex() et al) for multiple operations that need to be atomic. Imagine you have a set of shared data that needs to be modified all at the same time due to interdependency (interdependent but not derived from each other). Without CFLOCK/semaphore/mutex(), you cannot guarrantee consistency. If you see how a typical enterprise level RDBMS is designed, you would know that mutex()/semaphores are used all over to prevent collisions. I am not trying to say that I am superior compared to you. I am very certain that you know more than I do with respect to many things in computing. I am just pointing out stuff that you obviously do not understand. Web applications by definition are supposed to be designed for load. :) The single thread everything is kinda wrong due to scalability issues as Dave Watts have pointed out numerous times. I started coding back in college in 1994/95 (BASIC in 1984 does not count :P). Play algorithms and stuff. The fun stuff started in 1997 when I played with supercomputers and parallel algorithms. That's where I appreciate the need for serial access to shared and interdependent resources. Heck, that was also the year I was introduced to CFML. So, all in all, I have only 7 years of experience and compared to your two++ decades, 'tis nothing. :) When Simple == Elegant == Robust, that is a win-win-win. But if Simple == Elegant == Craps Out Really Badly Under Load, that is lose-lose-lose. I would rather have Robust+Scalable than simple but stupid. And, no, I am not offended by your statements. And I hope I have not offended you with mine. I just want the folks here in this list to appreciate the often underused, and yes, difficult to understand, CFLOCK. I am just very surprised that our resident jedimaster did not jump on this argument. :P ---------------------------- James Ang Senior Programmer MedSeek, Inc.

I've been a software engineer for over twenty years. But go ahead, continue to feel superior. After all, you are you, aren't you? And nobody else can be you like you can; wise old salt that you are. Congratulations. Try this formula: simple statement + irrelevent speculation = random idiocy I love this crap where relating simple experience leads to mass assumption of incompetence. It happened the last time I posted on this topic. I should learn. =================================== WARNING: Enabling the SINGLE THREADED APPLICATION option in the ColdFusion Administrator will lead to obvious and massive criticism and career degradation.
