Re: CF 8 Performance Problems?
This sounds exactly like the problem we ran into with one of our apps that is under very high load. Template cache settings and JVM settings do not make a noticeable difference one way or another in this case. I worked closely with Adobe support on this issue (bug 70837). Via some very simple code I wrote to reproduce the problem, Adobe found a bug in JVM 1.6 that basically hoses the template cache / classloading. Because JVMs 1.4 and 1.5 (and even a beta of 1.7 I tried) do not have the same problem as 1.6, Adobe saw these as feasible workarounds and thus marked this issue as a low-priority bug. We started using 1.5, and the problems went away immediately. I recommend anyone else with performance problems do the same. If another JVM is not an option, perhaps we can contact Adobe again and get them to push out a hotfix. quote However, if you are unable to continue in your production environment with the workarounds that you have found and would like a hotfix for this specific issue, let me know and I will inform the engineers to set a higher priority for this bug. /quote ~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;160198600;22374440;w Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:301740 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4

RE: CF 8 Performance Problems?
Correct. I should have made that point in my original post. It's Sun's bug, not Adobe's. We originally thought this was a CF 8 issue (back when CF8 was released), which is why I began working with Adobe (10/4/2007), and why they logged a bug (11/26/2007). They suggested, if a JVM change is not an option, to notify them and they would elevate the case again, though I doubt there's much they can do to code around Sun's classloading problem. -Original Message- From: Brian Kotek [mailto:[EMAIL PROTECTED] Sent: Friday, March 21, 2008 3:36 PM To: CF-Talk Subject: Re: CF 8 Performance Problems?

CF 8 Performance Problems?
Has anyone ran into any issues with CF 8 performance? We have a large application that we stress-tested on one of our CF 6 boxes. We then moved the code to our newer (larger and more powerful) CF 8 box, tested for compatibility issues (none found), and stress-tested it there. Its performance is much, much worse. Aside from tuning the settings in the CF Administrator, which had little effect, we haven't had much luck. We've been comparing settings between the servers, and nothing is raising a red flag there either. The application uses the exact same databases on both servers, and the same code. It has a couple of CFCs, other than that, it is made up of standard CFML pages. Has anyone else ran into something like this? It's quite unexpected due to the larger server and the supposed CF 8 performance enhancements. Suggestions are MOST welcome! We're on UNIX machines, if that helps. ~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;160198600;22374440;w Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:301597 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4
