I don't know about the jetbook,but the Sony reader has something like a 500Mhz processor under the hood. That's good enough to display about 5 pages per second or more. It's the combination of all; the processor goes into a sleep state, and when you swap pages it needs to come out of it, which takes a few milli seconds (I thought I read in the likes of 10ms somewhere).
But the processor itself is fast enough to give you perhaps even 10fps in B&W text mode. The only thing that taxes the processor (real bad) is color and larger than screen resolution pictures.

And there's also the delay from reading the info from the internal memory or SD card. That's an additional >2 ms.
