Form slowness inexplicable

Okay... I've had ONE user complain about the "slowness" of this form: http://www.it.dev.duke.edu/public/formtest.html The problem they're having is that when the resize the window or scroll or move it, it's slow.  Very slow. I don't have this problem.  My coworker experiences the problem to a lesser extent than the user, but he's got a super powerful machine (more powerful than mine.. faster processor, more RAM, etc). The difference is that both he and the user are on laptops and I'm on a desktop. I'm running IE7, Firefox 3, and Chrome and experience no problems. He's running IE6, Firefox 3, and Chrome.. only problem in IE6.  He upgraded to IE7 and still noticed the slowness. The user was also using IE but I'm not sure if it was 6 or 7. He says when he scrolls, it's spiking his CPU usage. Anyone got any ideas on this? -- Rick Root New Brian Vander Ark Album, songs in the music player and cool behind the scenes video at www.myspace.com/brianvanderark

That's interesting but... this form isn't flash, and it works fabulously in Chrome (and Firefox.. and IE on my computer)

No slowness for me, IE6/WinXP/3-yr-old laptop. -- Josh ----- Excess quoted text cut - see Original Post for more -----

I suspect he has some ActiveX control installled that's interfering with things.

If 1 user out of however many ever used the form (since it's a edu site, I suppose it's ALLOT) complains about something that hasn't changed... It's a PEBCAK error or a ID-Ten-T Error. Dave Watts wrote: ----- Excess quoted text cut - see Original Post for more -----

One user has complained .. out of several hundred.  But the problem exists on my cohorts computer as well just not as significantly.  and he doesn't use IE at all.. no weird toolbars installed or anything. The only commonality between the two users is they're both using laptops.. but one was an older laptop.  Both running Windows XP. rick

Is this user local?  Your only real hope is to take a look at their computer. Have them clear their cache and restart.  Take a look at what is running in the background. How much memory is installed?  Available? What toolbars are installed? Take the test page, and start removing pieces of the code until the problem goes away.  What was the last part you removed? Stuff like that is where I would start.  If you don't have access to your user's computer, it is going to be a lot harder, but it helps that you can at least reproduce the problem in part on your coworker's computer. ~Brad

Yup, already did that. > Have them clear their cache and restart.  Take a look at what is running in > the background. How much memory is installed?  Available? > What toolbars are installed? Well, Nate's computer (my web programmer cohort here) is a Dell Precision laptop with 4gb of RAM, etc.. no toolbars installed.. > Take the test page, and start removing pieces of the code until the problem > goes away.  What was the last part you removed? Good idea.. > Stuff like that is where I would start.  If you don't have access to your > user's computer, it is going to be a lot harder, but it helps that you can > at least reproduce the problem in part on your coworker's computer. Well luckily as I mentioned, another user (our other CF programmer) is experiencing the same problem on a less significant scale... he's gonna try removing stuff and see if he can figure out what might be causing it. -- Rick Root New Brian Vander Ark Album, songs in the music player and cool behind the scenes video at www.myspace.com/brianvanderark

His form isn't using Flash, it's using DHTML.
