DEVELOPING COLDFUSION 9 APPLICATIONS
Developing CFML Applications
Name
Description
User Agent
The identity of the browser that made the HTTP request.
Remote IP
The IP address of the client system that made the HTTP request.
Host Name
The name of the host running the ColdFusion server that executed the request.
Execution Time
The Execution Time section displays the time required to process the request. It displays information about the time
required to process all pages required for the request, including the Application.cfc, Application.cfm, and
OnRequestEnd.cfm pages, if used, and any CFML custom tags, pages included by the
ColdFusion component (CFC) pages.
To display execution time for a specific block of code, use the
You can display the execution time in two formats:
• Summary
• Tree
Note: Execution time decreases substantially between the first and second time you use a page after creating it or changing
it. The first time ColdFusion uses a page it compiles the page into Java bytecode, which the server saves and loads into
memory. Subsequent uses of unmodified pages do not require recompilation of the code, and therefore are substantially
faster.
Summary execution time format
The summary format displays one entry for each ColdFusion page processed during the request. If a page is processed
multiple times it appears only once in the summary. For example, if a custom tag gets called three time in a request, it
appears only once in the output.
The following table describes the display fields:
Column
Description
Total Time
The total time required to process all instances of the page and all pages that it uses. For example, if a request
causes a page to be processed two times, and the page includes another page, the total time includes the time
required to process both pages twice.
Avg Time
The average time for processing each instance of this page and the pages that it uses. The Avg Time multiplied
by the Count equals the Total Time.
Count
The number of times the page is processed for the request.
Template
The path name of the page.
The page icon indicates the requested page.
Any page with an average processing time that exceeds the highlight value that you set on the Debugging Settings page
in the ColdFusion Administrator appears in red.
The next to last line of the output displays the time that ColdFusion took to parse, compile, and load pages, and to start
and end page processing. This image is not included in the individual page execution times. The last line shows the
sum of all the time it took to process the request.
