So I went back and did some linear timings... yeah, I know they don't
tell you 'real world' performance but it was interesting nonetheless:
I ran these three tests in a long loop:
#1: <cf_tag> (with tag.cfm in same directory)
#2: <cfmodule template="tag.cfm">
#3: <cfimport taglib="." prefix="x"/>
<x:tag>
<x:tag> was the fastest - by quite a margin; next was <cf_tag>; slowest
was <cfmodule>. There wasn't a huge difference between <cf_tag> and
<cfmodule> tho'. Here's a sample result for 100,000 iterations:
cf_tag: 12148
cfmodule: 13497
x:tag: 9465
tag.cfm contains just:
<cfoutput></cfoutput>
The test file looks like this:
<cfoutput>
<cfset a = getTickCount()/>
<cfloop index="i" from="1" to="100000">
<cf_tag>
</cfloop>
<cfset b = getTickCount()/>
cf_tag: #b-a#<br />
<cfset a = getTickCount()/>
<cfloop index="i" from="1" to="100000">
<cfmodule template="tag.cfm">
</cfloop>
<cfset b = getTickCount()/>
cfmodule: #b-a#<br />
<cfimport taglib="." prefix="x" />
<cfset a = getTickCount()/>
<cfloop index="i" from="1" to="100000">
<x:tag>
</cfloop>
<cfset b = getTickCount()/>
x:tag: #b-a#<br />
</cfoutput>
