CF 9 Standard CFThread Limits

[SteveTX]

In the CF Admin for Maximum number of threads available for CFTHREAD:

"The maximum number of threads created by CFTHREAD that will be run concurrently. Threads created by CFTHREAD in excess of this are queued.  On Standard Edition, the maximum limit is 10."

In the PDF showing a comparison of various versions of CF:

"CFTHREAD is limited to two additional spawned threads in Standard edition."

It doesn't seem like both those statements can be correct. Can someone explain how the thread limit actually works in the Standard Edition?

Pete Freitag did some testing on this very thing a few years ago.  I suppose it still holds true (not sure because we use enterprise here).  From the posts that I have seen it looks like Standard is limited to 2 threads (spawned by cfthread).  Anyway, I guess the only way to be sure is to do some testing on your machine and fire up the monitor to check on the threads.

From Pete's discussion here http://www.petefreitag.com/item/708.cfm:

We have CF8 Standard in production and CFAdmin reports that 10 threads are the max, not 2 (I realize that the Adobe Standard vs Enterprise pdf lists 2). I've been using CFTHREAD heavily while developing web spiders and can confirm you can get more than 2 out of it. Server monitor should prove that if you're curious.

And of course Ben Nadel has a great post about cfthread as well:  http://www.bennadel.com/blog/1886-Ask-Ben-Processing-Files-With-CFThread-In-ColdFusion.htm

Interesting question, Steve. I don’t myself have a Standard license implemented to readily test: does that page have a field for you to enter a number? Does it let you set it to more than 2?

If it does not let you set it at all (I just can’t recall if it does), then I could understand the reasonable confusion. If it does let you set it, and to more than 10, are you then just wondering if it “really” takes as opposed to what you read in the other document? Either way, I do agree that it’s confusing and it would be nice if Adobe addressed it. They may not see this thread though.

Assuming you get no better answers here, I’d propose you ought to either file a bug report (http://bugbase.adobe.com/) or add a comment to the docs page where this is discussed:

Hope that’s helpful.
