Using Zena normalise a large (488 pages) PDF file. Open it through Zena viewer. Frequent turn pages makes the viewer stalled.

    JPedal (our third-party PDF renderer) does not allow the PDF file to be streamed, and thus the data must be converted to a byte array in our viewer and passed in one blob to JPedal. This will not be easy to fix as it would require modifying the JPedal source code. A temporary solution is to increase the java heap size to as much as practically possible.

    Is there any reason to keep this one open?

    Not urgent, but looking into a streaming PDF viewer would be useful.

    Worth wile looking at new pdf technology to see if we have new alternatives to stream pdfs for viewing.
