Can you link us to one, so we can do independent tests with it, please?

For example the Modula-3 reference manual, 100 pages, when scrolling with the mouse, pages can take more than 1s to render on a i7 system.

With native readers, it is almost instantaneous.

Unable to reproduce on a 2.6GHz Core i7. It's slower than the viewer in Chrome, to be sure, but not to the degree you describe.

There might be something up with your install--- run away plugin? I read lots of journal articles in FF, many in the 15-30page range with figures, with no problem on an old dual-core iMac.

My install?! As I mentioned, in all computer systems I have access to.

I just get the spinning wheel effect, while the CPU usage scales all the way up, until the whole document is downloaded, processed and finally displayed.
