      I think Chris had a while loop in one of the more commonly accessed pages that was failing to meet its exit criteria, and therefore looping endlessly. The loop we're suspicious about had to do with the advertising weighting system. We've commented out the offending piece, and are analyzing the failure conditions offline. I've fired off an email to Chris and hopefully he'll be able to read it before hopping on his flight back here. But in any event he'll be in Toronto early next week to replace all the duct tape and glue we've throw into his code ;) We also added 3 3.2Ghz servers which effectively doubled our capacity at the presentation layer. Still more to come... David

      So, what do you propose we'll do to Chris for not terminating his loops properly, eh? :-D -- Ich bin Joachim von Hassel, und ich bin Pilot der Bundeswehr. Welle: Erdball - F104-G Starfighter

                  How's the site speed and access for everyone now? We think we may have found and removed a spanner in the works, and we brought 3 new servers on. Anyone who is even mildly pleased can give kudos to Peter Zajac (peterz@dundas.com) ;-) David

                          No, he's just short sighted. As we will all see, including Anders, when the concurrent session count racks up tomorrow morning things will become slower than they are today. I would estimate that getting to where we need to be with CodeProject will cost about $400,000. David

                            This is getting a little overblown. It may not in-fact be an endless loop problem, or even something that relates directly to the advertising system (although I think it's hilarious that everyone has their shorts in a knot over the idea). David

                                    Lol, you're an interesting man Anders. No matter what happens, your statement that we wasted any investment on the expanded hardware is shortsighted, Internet genius or not. ;) That, we can take as fact, and is the core of what we're talking about. There's no question that CodeProject will run slower than the .001 second response times that people were seeing today when the concurrent sessions start piling on tomorrow. So, you can have the last word on this thread if you want. I'm out. David

                                      The endless loop scenario should be realatively easy to spot as load ramps up. You should see processor usage jump up in plateaus of 1/n where n is the number of processors. The length of the plateau should be about the timeout interval of the page.

                                        The endless loop scenario should be realatively easy to spot as load ramps up. You should see processor usage jump up in plateaus of 1/n where n is the number of processors. The length of the plateau should be about the timeout interval of the page.


                                        I can imagine the sinking feeling one would have after ordering my book, only to find a laughably ridiculous theory with demented logic once the book arrives - Mark McCutcheon

                                          I need to make a deal with some hardware manufacturers, that I'll add some random while (true); in the code, and they give me some percent of the server sale ;) So that little fix cost you guys $90k in not really needed hardware eh ;) - Anders Money talks, but all mine ever says is "Goodbye!"

                                          Anders I think, I understand a little of what you are saying. I know nothing about running a website. But in other realms of IT I have become a believer that now people are solving problem with brute force rather than well thought out designed solutions. This bruteforce is both in hardware and software. An example of this is the current OS bloat caused by MS with windows. (I know windows isn't an OS, but the OS isn't worth much without windows) Regardz Colin J Davies
