Why?

“Well, because.”

I’ve never understood that.

I have run a menubar CPU monitor for years (either MenuMeters on <OS X 10.4, or iStatMenus under Leopard), and it's appalling how some sites will pin the CPU - usually over something incredibly stupid, like WRAL's fancy new weather report page, which took a perfectly functional static image with text underneath containing the week's weather forecast, and replaced it with a Flash-based abortion that you have to scroll to see the forecast, and which seems to have been done solely for the purpose of allowing animated sunshine, rain, and snow - and which has the effect of raising my CPU temps from the typical 58 degrees or so to the 70 degree mark in seconds, and uses 70% of the CPU - for information that never changes after page load. Wish this practice of profiling were more widespread.</p> Boy, no kidding.

This is particularly glaring if you're unfortunate enough to be using IE (even IE8) and are suddenly forced back into the click-wait-click style of interaction.</p> I’ve found this to be a surprisingly noticeable advantage for the newer JavaScript engines: for many sites, this makes a very noticeable difference because it’s the difference between response time being over the threshold where things appear to happen as soon as you click.

CPU usage near max, fan on high, (and battery life shortend), sluggish performance, just to display blinky ads and who knows what else but not some useful function you really wanted and which reasonably warrants high CPU usage.</p> You really see this with a low-power computer like an Atom-powered netbook.

I would love sites to take load into account. advertisers will make that hard, but not impossible…

What would be nice is for G-mail to recognize that I want “old-school” on some devices, and “new-school” on other, so I don’t keep switching back and forth.
