Neil, Could you share your jvm settings? I would be interested to see what you have as compared to the "best practices" I have read.

We have recently had performance issues which could have been caused by a numerous amount of small things - we upgraded our hardware and also had to run extensive debug sessions using JVMStat as we found that with the old hardware and settings that Garbage Collection was taking over every 5 mins and indeed was leading to a "stop the world" situation a few tweaks to PermSize etc and we were god to go. We are still getting the odd large spike in activity, especially when we get around 1500 users at any once time. There is a definite problem with IIS in particular I think - Michael reckons it may be down to IISLockdown but I am not not sure as of yet.

A very bad approach for running enterprise apps, but there is no other way. My personal opinion about this; these stability issues (and there are an enormous amounts of people with these issues) should be the no. 1 top priority of macromedia. They cause a lot of distrust in the product. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Special thanks to the CF Community Suite Gold Sponsor - CFHosting.net http://www.cfhosting.net Message: http://www.houseoffusion.com/lists.cfm/link=i:4:185165 Archives: http://www.houseoffusion.com/cf_lists/threads.cfm/4 Subscription: http://www.houseoffusion.com/lists.cfm/link=s:4 Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4 Donations & Support: http://www.houseoffusion.com/tiny.cfm/54
