Time cffile upload

[s_filipowicz]

Hi everyone,

I want to time the upload time when using CFFILE

I thought I could take the tome before the cffile tag and then take the time after the cffile tg and use the Datediff to get the upload time in seconds. See example below.  But this gives me 0 seconds.

------------- Example ------------

<cfset startTime = Now()>

<cffile action="upload" destination="#application.upload_images#"  filefield="#variables.filename#" nameconflict="MakeUnique" accept="image/jpg,image/jpeg,image/pjpeg">

<cfset endTime = Now()>

<cfset uploadTime = DateDiff("s", startTime, endTime)>

---------------------------------------

How can I time the upload time?

Thanks!

Use getTickCount(), it's a lot simpler.

<cfset startTime = getTickCount() />

Do stuff

<cfoutput>#getTickCount()-startTime</cfoutput>ms

Thanks for pointing out the getTickCount() function, never heard of it.... but very handy!

Unfortunatly it doesn't solve my problem with the timing, I still get 0 seconds or ms

Ah, bear in mind it's not doing what you think it's doing.

The <cffile> tag is *not* uploading the file, by the time it's called the file has already been uploaded to the Web Server, cffile is simply moving the file to its destination, which is probably taking less than a millisecond and so showing as zero.

There are many threads on here about creating timers for uploads, and due to various technical reasons it's nowhere near as simple as you'd like I'm afraid

Ok thank you for your reply. I was also thinking in that direction but was hoping it was as simple as I initially thought.

I gues the uploading starts straight after clicking on the submit button on the upload form. O well it was not an important feature needed, just thought it would be interesting to monitor the upload times of users.

Thanks for your help!!

I guess the uploading starts straight after clicking on the submit button on the upload form.

Spot on, CF doesn't even get a look in until the upload has actually finished.

Glad to save you some time, if nothing else

The CFFILE tag that processes the upload doesn't actually have anything to do with receiving the file. By the time CF runs, the request has already been received in full by the web server.

So, you need to do your timing from the client in this case, not the web server. There are plenty of timing tools for Firefox and presumably Chrome as well. Load test tools do client-side timing as well.
