For example, when I click on a Facebook picture, the picture remains pixelated for about 30 seconds, then starts to clear up. Or when I watch YouTube videos, I can't watch them on HD without running into buffer issues. Windows 7 is just much snappier. It might be an issue with the graphics card.

Dualbooting Windows 7 64bit & Ubuntu 12.04 64 bit

Specs: CPU: Intel® Core™ i7-2630QM CPU @ 2.00GHz × 8 RAM: 8GB DDR3 HDD: 50 GB to Ubuntu & Remaining 1.5 TB to Windows

The interesting part: Graphics Card: On System Settings in Ubuntu: Intel® Sandybridge Mobile
Graphics Card: What it should be: Radeon™ HD 7690M XT switchable graphics with 1024MB GDDR5 and up to 5093MB total graphics memory

"webpages take longer to loo". I know it's a typo, but I lol'd. – belacqua Jun 6 '12 at 22:06
It could be because of flash too. And for the graphics card try installing the latest drivers. – nikhil Jun 7 '12 at 10:12
If I'm not mistaken, the Windows versions of various web browsers can somehow render webpages more quickly and efficiently because they can access proprietary libraries, etc. to make better use of your hardware, particularly graphics. In some cases this may be more noticeable than in others. – Christopher Kyle Horton Jun 7 '12 at 18:37

I'm not sure what's up with your graphics card being reported incorrectly, but when I first switched to Ubuntu I had a similar experience with loading web pages. The solution that worked for me was to specify different DNS servers. Open the Network Manager applet in the top panel and select Network Settings. Select the network interface you want to edit and click on the button that says Options. Click on the IPV4 Settings tab and under DNS servers enter:, This will use OpenDNS DNS servers instead of whatever your default DNS server is. It made a big improvement for me.
