CPU Usage high on certain pages?

[Richard Fangnail]

I was just looking at a few web pages and noticed in Task Manager that
CPU Usage would shoot up to 77% or even 100%. Is this normal?

One of the pages was wunderground.com, a weather site. Another were
Facebook pages.

Firstly, if you click on the "Mem Usage" column heading in 'Task
Manager' so as to arrange the items from using the most memory at the
top to using the least at the bottom. Then no matter what webpage has
been loaded, it SHOULD be the item labelled "iexplore.exe" that takes up
the referred to "shoot up" in memory usage.

If you are wanting to know if it is "normal" for certain web pages to
take up resources, then yes they can.

But, a website can do this legitimately, or because it is, for instance,
busy installing a resource-grabbing virus!

As a result, you have to use your common sense and judgement (plus
having AV installed) for questions like this.

If you are regularly visiting a website that provides you with a valid
service, such as the weather, then it's going to be 99% certain that all
is just fine.

Any web page that downloads Flash or Video will cause this.
Also web sites heavy loaded with high resolution pictures.

Hello,

This is normal, especially on Web 2.0 sites like Facebook and Digg which are
powered by JavaScript behind the scenes.

You will notice a great speed improvement by disabling JavaScript (Active
Scripting) and Flash (IE > Tools > Internet Options > Security > Custom
Level > Active Scripting > Disable > 'Run ActiveX Controls and plug-ins' >
Disable > OK), but note that this will reduce the functionality of many
sites
