AmEx's Website Has Java Script Demand Problems

Postby scoleman » Sun Dec 08, 2013 2:57 am

This evening while reviewing various CC offers and their sites my browser, Firefox, started using 100%+ of the CPU capacity... yeah, yeah I know ya can't have more'n 100%.

Well with a Mac, according to it's Activity Monitor, some really wild arse programs can, or at least appear to. Bottom line, whatever the actual usage is it's off the charts. And wreaks havoc on the speed and efficacy of browsing.

Took quite a bit of digging to realize that the Am Ex web site was the whole cause of this issue. That's after restarting FF and the computer several times over a couple hours trying to clear out whatever was clogging up the works.

Quite a feat for one ol simple CC web site given I've been running with three windows active, one having 30-35 tabs open at a time, multiple videos going, etc. for the better part of the past several weeks and not one bit of trouble, with FF typically less than 20% of CPU usage, with 5% or less when 'idling'.

Looking to obtain an American Express Blue Cash Card, but if that's the best they can do, running a web site such that it can't handle simple tasks like everyone else's can without overloading their users computer then it really makes me wonder how well they can handle the important stuff, notwithstanding all the praise they get for being such user friendly folks.

Installed NoScript which I'd been doing just fine without 'thank you very much' AE, until now, in order to get it under control soes I could have their site open without things gone all to hey. Which means so long as it's needed I have to dink around with NoScript for every other site when it wasn't at all necessary before.

While it 'appears' one can use their site anyway, I won't know for sure how well until I pull the trigger to join up, with their scripts blocked one gets...

'It appears that JavaScript is disabled within your browser.

To view the full site experience, you should ensure that you have JavaScript enabled ...'


Reckon we'll see... Sure hope it doesn't prove to be a requirement for every time I wish to access an account with them.

Sheeshhh...

I've never had a problem with AmEx's website. In fact, of the four issuers I have cards from, I believe AmEx to have the best website of them all. I primarily use Google chrome for browsing which causes issues with Discover's site but that's it.
Citi Forward ($10.1K), AmEx Blue Cash Everyday ($30K), Chase Freedom ($12.4K), Discover it ($5.5K), Barclaycard Arrival ($12.5K), L.L. Bean Visa ($5K). FICO 806 (TU), 812 (EQ), 806 (EX).

I browse Amex's site on my MacBook with Chrome. I have Ghostery and NoScript enabled. I haven't experienced the issue you bring up and rarely notice any issues when rendering the site.

Turns out FF and AE don't play well together. Had to go to Safari and no problems.

That said, I've been a major fan of FF for years and find it has very few issues for a wide range of sites and functions. I deal with at least three different banks, six different CC cos., three Ins. cos., numerous merchants, forums, etc. etc. etc. and NO problems. Just have to swap over to Safari when dealing with AE... unless the nice lady I spoke to at their CS dept. when calling to apply via phone has some success getting the PTBs to fix it as I suggested before signing off after she mentioned that the Amazon Prime deal is only good if one applies online. Something I did not see stated anywhere in all the legalese BS.

All in all a happy ending, especially after finding that our auto ins. accepts AE so making the $1000 cut for the BCP will be a piece of cake, if having to dole out a pile of cash to a dang ins. co. can be considered as such... ';)

Thanks for you response,

Steve

Normally javascript should not cause any issue. Like all the sites these days javascript, more specifically jQuery is a commonly used script in webpages. This allows users to have better user experience while using webpages. For example: like sliding animation, fading, etc.
In your case, may be the javascript was stuck in some loop (if java script caused the high cpu usage), or may be something else, there are numerous factors that can play the role.
Restarting the browser should fix the issue, and it should not be repeatable. I just did a quick javascript profiling on AMEX site, and all the scripts performed as needed, consuming few seconds, at most, consuming fair amount of memory to execute.
If its recurring in your computer, may be you need to dig deep to know what exactly is causing the problem.

Since Amex announced new updates to their site this past week, I am no longer able to do more than look at my Gold PRG card/info.

I can not navigate away to one of my other cards, or payment screen, or anywhere else on the site.

I have to launch FF to do anything.

Since you mention FireFox, it could be an issue with that browser. I haven't experienced that using IE.
