I tried that paintings PDF on my PocketBook Inkpad, and it _does_ take a long time to render the pages with the detailed images. Page 17 took about 30 seconds, while the others near the beginning took about 15 seconds each. That is too long for comfortable reading. I logged in while it was running, and saw that memory wasn't an issue. The device has 512MB of RAM, and the reading program (AdobeViewer) was only using about a third of that (about half if virtual memory is included). The CPU was at 100% while I was waiting for the page turns. The CPU is a 1 GHz ARM chip, which is pretty decent for an E-Ink device. I wonder if there is a lot of floating-point math being done, since that would have to be emulated on these devices?
