Why does certain PDF take longer to display?

I have two multi page (mainly containing drawings) pdf approx 80MB each.
File A, is a scanned file with approximately 60pages, whereas File B, is a published file from (I assume an CAD system) with approx 400pages.
In File A I can scroll and zoom very quickly and page rendering delays are almost zero. Whereas in File B scrolling to the next page takes 10s of seconds. My job requires me to "flick" through the drawings and zoom in and out very often and therefore making the use of Acrobat and PDF very difficult. These type of files are needing to be printed, which cause great delays at the printer.
Understanding why it happens may help in the next step of reprocessing of the PDF to increase the rendering speed.
Thanks.

If the pages are scans, there is probably just a single image per page, so there's only a single object on that page. CAD drawing can have hundreds to many thousands of individual vector and text objects that need to be redrawn when the view changes, and this can take a lot of time.

  • Why does my MacBook take long to boot up

    If I force shutdown my MacBook then restart it, it stays on the load screen for minutes sometimes beyond an hour. I have already verified and repaired the disks and permissions but it still takes long to load. Any ideas why it could be taking so long to reboot?

    The first thing to do is startup up in Safe Mode and see if the machine behaves acceptably.  There is a second knowldege base article that may help give further guidance.

    Welcome to our community
    Unless something has gone catastrophically wrong, you should never have to perform the uninstall/reinstall/reapply the patch hokey pokey. So that's just wasted effort. There is a simple way to perform what I call the "Factory Reset".
    I recently described how to do this in the thread linked below:

    I might question why this is needed at all. Perhaps you are unaware of some things that help you avoid issues with Captivate.
    For example:
    How many slides are in your projects? We normally recommend keeping projects somewhere between 50-65 slides as a rule of thumb guideline for the upper limit.
    Where exactly are your projects residing when you make edits? Frequently we see folks working with projects on a network drive. This is less than optimal and will often cause issues and slowness and project corruption. Work locally off your C drive and periodically copy the project the network server to be backed up.

  • Why does iPhone 4 take long time when finishing syncing?

    I have recently started noticing, after upgrading to 7.0.3 that my iphone doesn't work as well, crashes occur in apps and it's a lot slower to process.
    Then I went to back-up my iphone, to my Macbook Pro, as I always do and have recently done since upgrading to 7.0.3.
    It goes through the first stages of back-up at a regualr speed.
    But when it gets to 'Finishing Sync' .... well, it has been finishing now for over 30mins!
    I have alot of Apps on my phone, but have never had an issue with using them before upgrading.
    Can anyone give me some advice on what I need to do to prevent this or fix the speed of the sync.
    Can I do a partial back-up/sync of importnat things like iCal - when im in a hurry?
    My phone obviously won't back up properely if I eject it before it's finished? Love some assistance if anyone has any ideas.
    Thanks!

    My mac is running Snow Leopard 10.6.8.
    Any ideas?
    Thanks

    Hard wiring it into the LAN helped a bit but what is really slowing it down? WPA2?
    Thanks,

    could be the wifi speed as in 56Mbit vs. newer 300Mbit version
    or interfearing from other wifi networks which use the same channel
    or microwave or dect phones which also operate on the 2.4Ghz band

    Why does my ipad2 no longer receive photos on iMessage? Iphone works perfectly with iMessage photos. Ipad2 used to work fine. Is it an ios8 issue? Help!

    Hello,
    Where may I be able to contact and speak with a prepaid representative? Strictly through phone calls? (I am at work 12 hours a day)
    And I apologize for posting in the wrong area - I saw Apple support so I went here.
    I'm almost certain my phone is the problem. I have gone through resetting the network settings a dozen times on my phone, even did it on my dad's. Now my texts are beginning to do the same when I text my fiance.
    Resetting the network settings DOES work -- the problem is it will work for a day or two or for only a few hours - then I'll have to do it all over again.

  • Why does apple tv take hours to record

    Why does Apple TV take hours to record movies?

    Not sure what you mean by 'record movies'
    If you are trying to rent a movie and it's taking a long time before it starts then that is due to your connection.
    720P requires 6mbps for instant streaming
    1080P requires 8mbps
    You can switch to SD in the settings
    To check your connection go to speedtest.net

  • Why outlook2011 mac version* takes long time to boot with OSX

    why outlook2011 mac version* takes long time to boot with OSX

    Okay, so after doing all of the above, the computer still takes between 40 seconds and 1 minute or so to boot up, and the VersionCue messages still appear. However I discovered that the "kdcmond cannot retrieve..." messages disappeared after I disabled my ethernet connections. So at least I know that that had nothing to do with the extended boot-up time.
    I have heard that the more RAM you have, the longer it takes to boot due to the RAM count. Since I have 10 GB, maybe this is why?
    I've included the most recent Console messages below:

    Why does my ipod no longer play all the items in a playlist?  I have to go to each item individually to select it as it no longer goes from one item to the next.

    what kind of connection do you have? do you use the ipod 30 pin cable that connects directly to the head unit? it so, maybe you could get help on the alpine site, or a similar site?it could just be a bad connection. you may just have to go oldschool and use rca cables and plug those in...

  • Why does Maverick mail no longer search properly? I used to search for a name and it would find it in All mailboxes. Now it sometimes works, but mostly not. Any solutions?

    Why does Maverick mail no longer search properly?
    I used to search for a name and it would find it in One or All mailboxes. Now it sometimes works, but mostly not. Any solutions?

    I would like to add that Comcast is my internet provider. Perhaps that is part of the issue although the Connection Doctor confirms the mail box is connecting to the internet. No other function processes when Connection Doctor program is used to find the source of the issue. I have read forum posts but am unable to find a way to get my Apple mail to be delivered to my computer. It worked fine up until I chose to transfer mail to the Cloud. My mail account is a .mac account.
    Still hoping someone out there can help me.
    thanks,
    anne

  • Why does camera roll take up all my storage data and how do i get it free for space

    You might be able to re-enable it via this page : http://appleid.apple.com, then 'reset your password'
    You might then need to log out of your account on any iOS devices that you have  by tapping on your id in Settings > iTunes & App Store (Settings > Store on iOS 5 and below) and then log back in so as to 'refresh' the account on them
    If that doesn't fix it then you might need to contact iTunes Support : http://www.apple.com/support/itunes/contact/ - click on Contact iTunes Store Support on the right-hand side of the page

  • Why does the keyboard take over and type c's all across the search box (no hands involved)?

    Why does the keyboard take over and type c's across the search box (no hands involved)?

    There are only three possibilities. Either a dangling hand hitting the c key, or if you have a bluetooth keyboard connected and something is pressing a key, or you have some bad harware.  Eliminate the first two, and if you still have the problem, take it in for service or replacement
