DR800 PDF page loading is too slow.. How can I improve it?

bokjeid · 05-01-2010, 07:15 AM

When I turn to next page reading PDF documents, sometimes the loading time is too long - about 2~5 seconds? It is different case by case.
How can we shorten the PDF page loading time?
I can't bear it really.. Please help me!!

I have had similar problem with a very small number of PDFs. In the beta 2.0 release, most documents turn in a second, but I have a few that are taking between 5 and 10 seconds per page turn. iRex staff asked me to send them a sample document a week or two ago, which I did, and they said they have repeated the problem and are investigating a solution. So, all you can do is wait for the official release of 2.0 of the software from iRex, and see if they have been successful with the speed-up.

I'm somewhat relieved to hear that. I also hope it would be fixed next firmware upgrade!

In my case, it seems relevent with the type of PDF compression for monochrome images - JBIG2, ZIP, CCITT, Run Length or so. For instance, I changed it to ZIP then the loading time of the 'problematic PDF file' became normal. But it's not so convenient solution. It seems that a problem of PDF uncompression time caused the loading time to be so long for some PDF files.
