Admittedly... somebody decided to disable CFCONTENT on our shared servers for reasons I've never quite been able to unravel.. and they still haven't approved my reccomendations to support the bloody thing, so I may well have missed it ;> None of my apps are particularly CFCONTENT intensive.

The default has been as an extension every time I've run it up to date. That may be tied into server conditions or the fact that its mostly upgrades from CF5.0, but my experience has been extension only thus far. ISAPI filters and I have a history of abhoring each other. So I'm not frothing at the opportunity to run off and try it. But in my admittedly biased opinion (ISAPI filters are just a sadism exercise to torment server admins, they serve no actual viable function beyond that, I don't care what anybody else thinks ;>) As for Win2K, I'm not sure what the default settings for application isolation in IIS are; I thought it used "Medium", in which case it would use DLLHOST.EXE to run ISCF.DLL. At any rate, when I configure a server, I always make sure it's set to "Low". Low will consume all process requests in the inetinfo.exe... I think you actually mentioned that earlier in the thread... But anyway doing that makes it a royal pain in the neck to troubleshoot if you're running multiple site instances on the same slot. The performance hit is negligable IME. Since I generally stack two or three sites at least on a server, I generally run medium by default, or high for servers that I'm worried about isolating. When you set high isolation, IIS will attempt to balance out excessive memory usage. The exact process is either poorly documented or just not documented, (IE I can't find the damn thing) ;> In 2003 you can set up the processes to drop at resource consumption markers, and all valid session/client management data will be transfered to a new instance of the process, the old process will be terminated. Effectively an automated purge of racheted memory with customization. I presume 2000 has a simmilar, if less intelligent and more automated control. >> I'd suspect if your DLLHOSTS are consuming ASP resources out >> of hand, you probably need to check into your ASP >> applications rather then CF. > Most of the servers I've worked with have only been running CF applications > - and typically, only one of those.

I've admittedly got a high portion of ASP spread out across the server farm, heathens that I work with and such, but its quite literally our biggest pain in the neck with CF on shared servers - trying to identify which slot on a share is consuming server resources. I would truly adore being wrong, but with CFCONTENT disabled admittedly, I've seen one of our CF 5.0 boxes pushing 90% availible system resources (RAM and CPU) devoted to cfserver untill the server decides to take a small vacation and stop playing, while 40 slots are isolated and running sepperate dll's that are between them consuming a rounded off 0% of anything. If anybody does have any suggestions on how to isolate the site instance responsible for server resource consumption on IIS 5 with cf 4 onwards, I'd deffinetly be keen to hear. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Archives: http://www.houseoffusion.com/cf_lists/index.cfm?forumid=4 Subscription: http://www.houseoffusion.com/cf_lists/index.cfm?method=subscribe&forumid=4 FAQ: http://www.thenetprofits.co.uk/coldfusion/faq This list and all House of Fusion resources hosted by CFHosting.com.
