Memory & CPU stats during web browsing...

I've noticed that my netbook grinds to a halt when I browse the net and it doesn't matter which browser I use.

I'm using chrome at the moment and have 3 tabs open. One is for this post and the other is Scrabble on Facebook (3rd is just google). I know scrabble is a java app so it might be a bit resource hungry but do the figures below look right to you?

chrome.exe ~125k & 45-55% CPU usage
chrome.exe ~40k 30-35% when the tab becomes active (scrabble)
chrome.exe ~30k

I stopped using Firefox as I thought the new version with Adblock Plus was the issue but Chrome is exactly the same.

I've ran CCleaner & MS Essentials and I'm clean although I did copy some files from my old HDD and MS Essentials picked up this trojan Win32/Meredrop which seemingly is "sever". To be honest though the netbook was slow before this.

Any ideas? Samsung N140 - Atom 1.6GHz & 1Gb (upgrading to 2Gb this week).

Cheers guys

Ross

I have just opened one page in Chrome; to make this posting.

Task manager shows three entries for chrome 13K, 29K and 25K.
CPU usage when idle goes between 0% and 6%. The only real increase is when the Flash banner at the top of the page transitions to a new image, then the CPU usage can go to more than 50%, but only briefly.

This is on an old Pentium M 735 1.7GHz laptop, with 2GB ram. So not much more processing grunt than your Atom, but more RAM.

It is possible that the high CPU usage is reflecting paging activity because of limited RAM, that is the only benign explanation that comes to mind.

See how you get on once you have upgraded the RAM.

BTW I am running Chrome 4.0.249.11 on XP Pro SP3

Disable flash, see if that has any effect?

Although I suspect not if you are blocking adverts already.
