On my Tungsten, the biggest slowdown I encounter on a regular basis in any
application (now that my JPEG viewer has an ARMlet) is when Plucker
initially tries to load a page.
For example, I downloaded a longish document from the Project Gutenberg
archives and converted it into plucker format. After conversion, this
document is 8360k using Zlib compression. As you're no doubt aware,
Plucker divides it up into smaller pages (64k?). When I go to a new page
of this document, I have to wait around 10 seconds before I can page down
to the next page. And, this page is literally just text. Would an
ARMlet help with this?
