I am doing some performance test on a site running on ColdFusion 8 using
FusionReactor. There is one script that consistently ends up on the top of the
long running requests list. The script is very simple - it grabs a PDF file
that already exists on the files system and streams it to the user.
<cfif fileExists( filePath & fileName ) >
<cfheader name="Content-Disposition" value="attachment;
filename=#fileName#">
<cfcontent type="application/pdf" file="#filePath##fileName#">
<cfelse>
<cfheader statuscode="410" statustext="Gone" />
<p>We're sorry, but the page you have requested no longer exists on our
site.</p>
</cfif>
The PDF files in question are pretty small ... 1 to 2 MB. In some cases (but
not all), the request logs in FusionReactor are showing this script running for
200+ seconds.
Does anybody have any ideas why this would be happening and is there a better
way to stream PDF files that are not web accessible (i.e. the user has to
register, then they get the file streamed to them)? I am not looking to change
the workflow - i.e. copying the file and sending a link by email etc. I have
streamed files like this before and have never seen these kinds of performance
issues.
Thanks for any input!
