    On the other hand. Adobe reader just got updated with and performance boost and annotations. Really good stuff for a free app

    I also found the ASUS Transformer Prime surprisingly slow in PDF handling.

    I have testet some PDF Viewers with the same big colorfull RPG-PDF:


    Here are the results:
    • Adobe Reader:
      Starttime*: 30 sec
      Time for jump to page #: 7 sec
      Search': 14 sec
      Display: correct
      Settings: few
    • Polaris Office:
      Starttime*: 8 sec
      Time for jump to page#: 2 sec
      Search': 7 sec
      Display: simplified / partially wrong (Background pictures not there)
      settings: minimal (Zoom)
    • MyLibrary:
      Starttime*: --- crash
      Time for jump to page#: sec
      Search': sec
      Display:
      Settings:
    • Mantano Reader Free:
      Starttime*: 16 sec
      Time for jump to page#: 4 sec
      Search': 12 sec
      Display: correct
      settings: few
      else: slow reaction onto touch input
    • eZPDF:
      Starttime*: 5 sec
      Time for jump to page#: 6 sec
      Search': 12 sec
      Display: correct
      settings: many
    • EBookDroid:
      Starttime*: 20 sec
      Time for jump to page#: 19 sec
      Search': no search function
      Display: correct
      Amount of Settings: extreme (with a lot of stuff I don't understand)

    *Time from touch on file in file manager until full visibility of title page in balanced modus.
    #Time for jump to Page 77/76 (Reader/Book) in balanced modus.
    ' Time for search (special Word only on page 98) from search start until compleat build up.

    I should report that the same PDF shows a much better handling on a iPad 2.

    Its pretty strange really, I know that ezpdf had some problems sith enabling gpu, so they had to remove it.

    Its tegra that is the problem or the app devlopers that are not using it fully? But it is readible, I get a 2 sec rendering lag with ezpdf every three pages, two pages are prerendered, nobody reads that fast anyway. The pdf im using is 80mb with 400 pages with minmium three highres pictures on each slide

    I was struck by this as it hadn't been my experience, so I opened up my Prime and tried opening the pdf of the Prime 201 Manual (69 pages, lots of images, 4.59 mb). It opened in My Library in about 3 seconds, and on changing pages it takes about 2 seconds to sharpen into focus. In plain Adobe Reader it took about 7 seconds to open but focuses almost instantly. Office Suite Pro opened in about 2 seconds and takes a couple to render each page.
    In comparison, opening a pdf in Adobe Reader on my brute of a desktop PC took about 3 seconds to open and rendering is instantaneous.
    The same exercise with the 94 page 2.2 mb Criminal Law Review (almost all text), was slower by about 1 second all round.
    So it isn't brilliant on the Prime, but comparable with a PC and the lag in rendering in Adobe reader isn't a serious problem - how long does it take to turn the page in the hard copy Criminal Law Review anyway? (3 seconds; I checked).

    I guess every bodies needs are different. I wish to use the TF201 for reading technical manuals. The largest is 230Mb, 5700 pages.

    To be honest the 201 struggles. EZPDF is by far the best. Sometimes once one has located the relevant section I do need to turn a number of pages in short succession. This is where the 201 is not great. I also seem to have this issue on smaller pdf's. I think EZPDF was better when it had the GPU rendering option.

    I agree that ezpdf is the most capable. Overall I am a little disappointed since the Prime has the hype of being a very powerful device, and runs games with intense graphics very well but a simple process of rendering a document seems to be a chore. Reading the comment about the iPAD2, I would have expected the Prime to perform better. Making an assumption, I guess this would be an example of the difference between an open source device (Prime) and closed (iPAD). Programmers for the open source have to write for a wider range of devices with varying capabilities whereas the closed source solution know exactly what hardware their programs will be running on.

    Ezpdf crashed a lot for me. I have been using Repligo and love it. I am an architect and when i do walk throughs of construction sites I go through a lot of documents, making notes and Repligo handles the large documents.

    RepliGo Reader fro PDF

    oom I have used RepliGo Reader on my Transformer formany months. Can read PDF files in naive format, zoom in and out, and even read in a mode that takes two column formatted files into one column. You have full control for annotations, notes, etc. and see al yur notes in PDF on a PC. Worth the $10 cost.
