I know and understand the purpose of fusedocs and by no way I'm I against it. (Trying to dodge any possible bullets). Ok here is the question. On a web server with a heavy load is it possible that the increase file size could cause or aid in performance issues. In this case would it be better to create a separate file with the fusedoc and make a single line reference in the template to it." My gut feeling was that CFAS munches through comments without skipping a beat. I wrote a little test to verify this hunch. I created four templates: 1. inc_comments.cfm with the Fusedoc header from the CF5.0 Fusebox corefile. 2. inc_blank.cfm with a single blank line. 3. test_comments.cfm with a cfloop to cfinclude inc_comments.cfm 50,000 times and time the results. 4. test_blank.cfm to test inc_blank.cfm in an identical manner to #3. The test templates look like this: <cfparam name="url.loops" default="50000"> <cfset start = Now()> <cfloop from="1" to="#url.loops#" index="i"> <cfinclude template="inc_comments.cfm"> <!--- the blank test uses inc_blank.cfm, of course ---> </cfloop> <cfset end = Now()> <cfoutput> <h1>Comments Test</h1> <p>Iterations: #url.loops# <p>Start: #TimeFormat(start, "hh:mm:ss")# <p>End: #TimeFormat(end, "hh:mm:ss")# <p>Duration: #DateDiff("s", start, end)# seconds </cfoutput> Results: Both test pages run 50,000 iterations in 37 seconds on my development server. I see no real difference between them. The time spent in the actual inc_* files is negligible compared to the time in the test_* files.
