Slow safari scrolling

[rasmusDoh]

Anyone know why my Safari takes up to 70% CPU when scrolling up and down webpages. Makes the whole computer super laggy!

Closed all webpages with Flash on them and the problem's still there.

Also tried resetting Safari and emptying it's cache. It made it faster for a few minutes, but then the slowness was back.

Can it be related to my hard drive (got almost no page-outs)?
Any other ideas?


Thanks

Safari's using 70% of 4gb?!? Have you compared different browsers?

No, 70% of the CPU.

FireFox is pretty laggy too.

Anyway, the main reason is that i just did a full erase / clean install - and i really don't get how Safari can be this slow right "from the start".

Any possibility that it could be a hard drive issue?

Safari acts just fine, when "not doing anything".

I mean i obviously get that it'll have to use some CPU to load new webpages and to scroll up and down on open ones.

But isn't peaks of 70-80% CPU a lot? It's only when i scroll.

The high CPU usage doesn't even make my computer slow most of the time. Only in some of those "peaks" i get a slight bit of "hang time".

The thing is don't get is why Safari acts like this on non-flash, very simple websites - nothing heavy to load when scrolling.

Am i really just being to sensitive?

I've thought this too after reading a couple of your threads, no offense intended by it, I'm not sure really. My 2006 Macbook doesn't hang when using Safari and then going to another app, even another browser so if its experiencing the issues you say, then there must be some sort of problem with the hardware.

The reason is that i really did have major hangs before the clean install.

Followed the advice i got and have been using the computer without my external drive and without restoring anything from my Time Machine.

Just kinda did everything i could to try and "reproduce" those beachballs - to get a final indicator of whether or not it is an hardware issue.

So it might very well just be me searching to hard for those beachballs to not notice that maybe the problem is gone.

What i've been trying to find out is if my hard drive is broken.
So, say my Safari was a bit slower than it should be - that wouldn't even have something to do with the hard drive, would it?
I guess Safari "performance" is solely CPU and RAM?
