Dakar website - eating my computer!
 
I've tried the Dakar site in both Firefox and IE on Windows XP - in both cases my machine starts to run really really slowly - when I look at the CPU usage (ctl-alt-del and click on the 'performance' tab) it's running at 100%.... odd

When I shut the Dakar site it drops to normal again - most strange.....

No mate

Mine too. Shot up to 100% CPU and stayed there. Most annoying not even my 'specialist' sites of interst do that.....

Based on a quick check, I got a similar result to Martyns. It peaked, briefly, at around 84% and then settled down at about 20%.

Did you try IE7?
 
I'm afraid to say it in public...but totally no issues with IE7... (4%-peak-4%)

Matt, do you still have IE somewhere tugged away on your system, maybe give it a try.
[edit] Oops, I should have read your message better you started with checking different browsers, sorry [/edit]

I get the same thing in IE too :-( Most irksome... thanks for the advice though.

MacP1 - thanks - glad to know it's not just me!

ahhh now that's interesting - just fired it up on the Mac in Safari and the CPU goes crazy... peaks out and then drops to 50-60% well above normal tick over speed.... there's something on that page that does not play well with others... more investigations I think.

flash-player?
 
Your flashplayer up-to-date?

I'm working with XP, Flashplayer 9 installed, maybe version-checking takes a big chunk.

That would be a massive amount of CPU time for a version update - but okay let's go with that!

Yeap flash up-to-date on both the PC and Mac - PC peaking at 100%, Mac at 54% then not dropping...

Some more investigation...

The site is calling over 82 external objects, there are 74 images, and it's calling 5 external scripts and not to mention the CSS which is bloody massive....

That's one heavy page but still doesn't explain the CPU use - it has to be one of the external scripts doing something 'funky'.

Why can't people just keep things simple!?

Lot's of people don't know or even realize what's going on behind the screens.
Although I reckon this is not the case with such a proffesionally build website, most people don't have a clue how webpages are build and the difference between content (text), design (how it looks), serversidescripting (behaviour) etc. Which btw isn't a shame or fault.
Others make things overcomplicated because they can, or just because their website-building-software creates them like this (old versions of dreamweaver and frontpage were known for this).

All these external images/scripts and other atributes can cause slow downloading a page (serverside), but doesn't explain the cpu time used(clientside) or the page must force the browser into some sort of a loop, which would be a real fault.

I thought about your security measures (firewalls/virusscanners/popupkillers/phishingfilters) but this wouldn't explaine the same behaviour on a mac, or would it?

No it doesn't explain the behaviour across both the PC (IE & FF on XP) and the mac (Safari & FF on 10.4.1) - it has to be one of the scripts running on the site - I need to get it on the test bench at work to diagnose the issue properly.... isolate and diagnose.

btw - I really wouldn't call that a 'professional' site... it's dreadful, both technically and design wise (YMMV). I don't generally criticise any website because I know first hand how difficult it is to get sites going in the first place. But when you have the budget and world wide following of the Dakar you'd think they could come up with something a little more professional... perhaps I'm being overly harsh but it really winds me up when large organisations who have the know-how put something out there that hurts peoples machines because they've not tested it properly.

At the moment I can't follow the race on the PC at all because of the memory leak (I'm guessing here can't tell exactly what the issue is until I've got in there properly) and the Mac only plays ball because it's only eating up one of my 2 processors.

Tried it at work no problem in CPU performance.
