I can hardly add more. :-) Good summary, and thanks for the kind regards, Ajas.
Really Frank (and others in that boat), it's so true: if you regard CF as a black box which when it "hangs" can only be "restarted" to "make the problem go away", you're really not solving the root cause problem. A tool like FusionReactor (or SeeFusion, or the CF Server Monitor, if on Enterprise) can be so vital. If you need help learning how to use FR particularly, besides the ample docs, they also have training (which I wrote and teach), and an awesome mailing list (where I and others actively help people solve problems). You can also hire folks who can help you interpret what you find, to connect the dots and solve the problems (hopefully) quickly. Besides myself, there are many others who do that sort of consulting, and I list them at http://www.carehart.org/cf411/#cfassist. /charlie arehart char...@carehart.org Providing CF and CFBuilder troubleshooting services at http://www.carehart.org/consulting From: ad...@acfug.org [mailto:ad...@acfug.org] On Behalf Of Ajas Mohammed Sent: Monday, January 31, 2011 11:17 PM To: discussion@acfug.org Subject: Re: [ACFUG Discuss] CF9 Performance Frank, here are my thoughts as far as performance optimization is concerned. I have solved my company's dreaded performance problems, thanks to FusionReactor and good advice from this group and more specifically Charlie Arehart. Thank you all. :-) 1. Get FusionReactor. Trust me, you will never use ColdFusion without FusionReactor next time. I guarantee it.For 300 dollars you will not go wrong. 2. FusionReactor will let you monitor all requests i.e. running or completed. So you can look at what requests took lot of time. 3. Even better, if a page is running slow, you can go and view exactly on which line number the code is stuck executing. Brilliant feature to solve performance problems. I love it. 4. You can view system metrics to see your servers health like memory, cpu usage, currently running request count all in one screen. 5. You can kill a request. Worst case scenario. There are exceptions but still there is an option. I can just go on like that. No kidding about that. Its an awesome tool for CFers. Now to the other important point. You didnt mention much about your configuration. How much memory you have available? things like that. If you can tell us that, we can help you better. Now you do say, its because of images in pdf. So let me ask you this, are you using local images or images from a url. If you are not using local images, then look at localurl = "yes" attribute that was added to cfdocument in CF 8/9. I would also look at the image you are using and check for the famous issue posted by Rupesh Kumar http://www.rupeshk.org/blog/index.php/2007/12/images-and-cfdocument-performa nce/ Finally, have you looked at any of the logs in ColdFusion to see anything obvious? Let me know if you have questions. HTH <Ajas Mohammed /> http://ajashadi.blogspot.com We cannot become what we need to be, remaining what we are. No matter what, find a way. Because thats what winners do. You can't improve what you don't measure. Quality is never an accident; it is always the result of high intention, sincere effort, intelligent direction and skillful execution; it represents the wise choice of many alternatives.

About 3 times a week I am getting a "The Request has exceeded the maximum time limit." It is happening on different pages and different tags. I know I can probably increase the global timeout value, but I would rather fix any real issue instead. Here is the question... We are on a small budget, I can get the owner to spring some cash, if it is really necessary. What would be my best option to find out the root cause of the issues? We are using CF9 Standard. I know the performance monitor in enterprise is decent, but for the $6000 upgrade cost, he won't be happy if it does not get me to the right results. (he'll deal with it, but I wouldn't like spending that much if I don't get my answer.) Is fusion reactor a better choice than the CF9 Enterprise upgrade? Does anyone else know other good choices? Right now my *guess* is that our large picture based pdf files are being created at the same time limiting overall resources slowing down the other pages. It would be nice to see what the resources are on the machine at the time of the error. To add to the complexity, IIS and MySQL are all running on the same server. (It is a small enough site, I have never seen more the 300MB of RAM allocated to MySQL.)
