John: How do you increase the number of concurrent template requests in coldfusion 9?
Jesse: I am thinking. Isn't this a setting in the coldfusion administrator under request tuning?
John: Are you sure?
Jesse: Yes I am sure it is there i looked it up see "Maximum number of simultaneous Template requests" and "Maximum number of running JRun threads".
John: Okay have you tested it?
Jesse: No, wait i will test it. Just hang on a sec.
John: (taking a small cup of coffee and reading a post on his favourite website)
Jesse: Hmmm, John i tried setting up 35 simultaneous requests but for some reason i can only get up to 25 simultaneous template requests.
John: I know you are running IIS 6.0 right?
John: Read this article and try again: Adobe website
Jesse: What the heck.
Jesse: Why is there a setting called "Maximum number of simultaneous Template requests" in the coldfusion administrator when this does not work. And why do i have to set this in some config file placed deep inside coldfusion.
John: (still smiling) Only the coldfusion God knows.

If for some reason you do not wish to goto the adobe official website, below the article they posted on how to increase the number of simultaneous template requests.
IIS 6/IIS 7 for ColdFusion 9: Increasing the Number of Worker Threads
While using IIS6 for ColdFusion 9 (or ColdFusion 9.0.1), owing to heavy load, if you encounter performance issues, you may increase the number of worker threads.
Go to the directory cf_root\runtime\lib\wsconfig\1.
Note: In multiserver scenarios, the location is jrun_root/lib/wsconfig/1. 1 indicates a single IIS website. If you have configured multiple IIS websites, the number can change accordingly.
Open the file jrun_iis6_wildcard.ini (jrun_iis7_wildcard.ini if you use IIS 7).
Note: By default, maxworkerthreads is commented.
Change the value to 50 (maxworkerthreads=50) from the default value of 25.
Restart IIS 6/IIS 7.
Note: The Maximum number of Simultaneous Template requests (Admin > Server Settings > Request Tunings > Request Limits) must also be increased accordingly.
