Thanks for the link. I read through your and Steven's blog posts. However, something that complicates things (I think) is that our environment is like that of a web host: We have multiple CF instances per server, and in many cases, many sites per instance. It would be hard to do a real-world load test on this, I would think (aside from tinkering with production during peak hours).
Also, CFMX *8* seems to have at least four different places where you can set a max requests value, so there are even more variables to contend with now. I think I'd have to defer to a better-informed person's guidelines as to what is a "middle of the road" starting value for these things. I wouldn't mind having the option of a single, more crude overall max request setting, actually. Further, my question about Windows-specific tuning recommendations still stands. I would guess that the Windows Server 2000 Adobe recommendations (including registry hacks to networking) would be applicable to 2003, but since I'm not an expert in this area, I wouldn't mind a sanity check there, either. By the way, here are some shorter URLs that will survive wrapping better: ColdFusion MX: Tips for performance and scalability http://www.adobe.com/go/tn_18540 Windows platform-specific performance settings http://www.adobe.com/go/tn_17277 Thanks again, Jamie On 9/10/08, Mark Kruger <[EMAIL PROTECTED]> wrote: > Jamie, > > Testing and experience are your best guides.
