Hello, Some websites (kfi640.com and radio station WCCO's player come
to mind) cause my oldish 1st generation G5 iMac to max out at 100%,
the fan goes to its highest speed, and the temperature goes up to 178
degrees F. And while I have no knowledge of computers (that's why I
own a Mac, right?) for some reason the word "Java" jumps in to my
head.
More likely that the word "Flash" is involved.
I thought my laptop's battery had suddenly halved in capacity. It turned
out to be due to a web site I'd left open which had some stupid and
seemingly minor Flash animation (probably in an advertisement) which had
maxed out one core on my MacBook Pro and was rapidly chewing through the
battery.
I had a quick look at http://www.wccoradio.com.
It makes heavy use of Flash on its web site. Safari on my MacBook Pro is
generally sitting at about 60% CPU usage just having this web page open
(both the main page and listening to the radio).
I can't test kfi640.com because they don't allow access to its audio
stream outside the US.
Any thoughts? I plan to purchase a new iMac in October and I hope
it won't have the same characteristic. Thanks.
It will if you visit web sites which have badly written Flash. Probably
not as bad as an iMac G5, given the evidence of my brief test.
There is a very good reason the iPhone's web browser doesn't support
Flash. The iPhone's battery would run flat very quickly just from
visiting web sites which use Flash.
Yeah, all that flash/javascript/java(/activeX?) eye-candy is a real
cpu sponge. I have to wonder if an argument could be made that the effect
of millions of PCs parked on these over programmed sites is a waste of
energy. Instead of going essentially idle after loading the page, so
much cpu is consumed that the fans have to come on. What's the difference
in power consumption between idling on a page with nothing more than an
animated image and on a flash heavy page? Maybe if flash got tagged as
"ungreen" if it would cause Adobe to take some measures to reduce its
cpu utilization, or maybe provide a power-saver like capability within
flash. (After 2 min, they are impressed enough, power back.)
Another wasteful annoyance is pages which unnecessarily access the Internet.
One web site I frequent has a Flickr thingee on its homepage which
constantly updates a set of pictures. Not nice if one is running
tethered and trying to avoid paying for excess bandwidth.
The problem, of course, is web developers and marketeers who have no
consideration the effects of their excess on their audience as long
as the page looks jazzy on a powerful system with a fast connection.
