Hi,
This is a question regarding the *performance* of using
ThisTag.GeneratedContent inside a custom tag �
Here is an example:
<cf_pageBody>
� lots of generated html code (worst case: say an online report: 1-2 MB) �.
</cf_pageBody>
Will ColdFusion save this very big string chunk into a new variable
�ThisTag.GeneratedContent� for use in the custom tag?
If so, is this a big hit on performance and memory? (think in terms of
traffic / site load).
OR: is the ColdFusion engine doing some trick by placing pointers around
some output stack (in order to save on performance/memory)
Next, does it make a difference if I don�t reference the
ThisTag.GeneratedContent inside my custom tag? (in other words, I
just let coldfusion automatically dump the generated content out�)
Basically, my tag would do the following:
<cfif ThisTag.ExecutionMode IS "START">
<body �>
<!--- my body header --->
<cfelseif ThisTag.ExecutionMode IS "END">
<!--- coldfusion automatically dumps generated content --->
<!--- my body footer --->
</body>
</cfif>
� would the above avoid a performance/memory hit? or will any
ThisTag.GeneratedContent performance hit be incurred even if its not
referenced?
.. basically, because some blocks would contain large html files (online
reports), I wanted to know if ThisTag.GeneratedContent would slow things
down, especially with increasing traffic/load.
To get around any performance hit, there would be two alternate solutions:
(1)
<cf_pageBody_start>
� my html body �
<cf_pageBody_end>
(2)
<body>
<cfinclude = �body_header.cfm�>
� my html body �
<cfinclude = �body_header.cfm�>
</body>
� I would much prefer using <cf_pageBody></cfpageBody> if the performance
hit is negligible.
Thank you for reading this long post!! Any insights are greatly
appreciated!
Michael
