Ubuntu - slow Image Viewer

I have Dell Precision with i7 and Nvidia Quadro 2000M.

I have many 12MP (5MB JPEG) images from my camera. Image viewer on ubuntu needs 2-3 seconds to show next image. Windows 7 does the same in no-time, ps3 also, even my IPad is incredibly fast...

Is is possible to do something in order to improve performance? Maybe it's possible to enable hardware acceleration?

Which viewer you used in Ubuntu? In my experience, Shotwell is much faster than the default Image Viewer, as the latter apparently doesn't pre-load next image.

Also this is disk operation, so if your Ubuntu running on an old drive and Windows 7 running on SSD that could make the difference too.

Cheers,
