first of all i know, i'm sorry, this sound like the classic silly question "my computer is slow this morning" but if you keep reading you may find out it's not.

On 2 (identical) computer of my network (100+ computer) Adobe PDF Reader open pdf files very slow (about 20 to 30 seconds per file and when the file is opened, if the file has multiple pages, the scroll is "laggy")

What i've tried:

  • Adobe Reader versions 9, 10, 11 all have the same problem
  • other PCs in the same GPO with the same group policy etc don't have any problem
  • Fox it reader runs fine but for policy reason i'd prefer to stick with adobe reader for all machines in the domain
  • I tried to open PDF files from local hard drive, USB drive, Network drive all have the same problem
  • No matter the size of the PDF (100kb to 10Mb) the loading time is still the same (20-30 seconds)
  • No matter the type of pdf (image, text, mixed, optimized, not optimized) the loading time still the same (20-30 secs)
  • If i open adobe reader without opening a file it opens in a seconds like it should do, but when i hit open a pdf file it just frooze for the, stated above, 20-30 secs
  • Updated the graphic driver with no appreciable changes
  • All other programs etc run smooth (autocad included).
  • I've tried 2 different antivirus (and without antivirus): Symantec endpoint protection, kaspersky endpoint protection

What i think:

  • Seems to be a rendering problem those 2 machines but i can't pinpoint where exactly is the problem. These are the only 2 workstation in the network to be affected.

It seems like you have tried everything except fiddling with the preferences and plug-ins i Adobe Reader.

It wouldn't hurt to go through this and report back: http://www.wikihow.com/Load-Adobe-PDF-Files-Faster

Can you post the relevant parts of your link here, as to avoid link-rot? Link-only answers are generally not a good fit here at SU. –  Doktoro Reichard Dec 15 '13 at 0:43
    
Thank you, i'll try and let you know! –  eldblz Dec 15 '13 at 17:39
  • Does this happen no matter what user account is logged in? If a different user account or local administrator doesn't have this problem, backup the user's data, delete the profile, login as that user to recreate the profile, and then restore the user's data.

  • Check if there's any shortcuts in the user's profile pointing to a network drive that doesn't exist.

  • Try removing all Outlook and Internet Explorer plugins on these system if any exist.

  • Check Add Remove/Programs or Programs and Features for any Adobe Acrobat or Adobe Reader plugins that may only exist on these systems.

  • Delete all "Adobe" folders in all Application Data or AppData folders in the users profile and see if the problem recurs. You may even go so far as to delete any "Adobe" keys (or rename to Adobe.old - look in HKLM/SOFTWARE and HKCU/SOFTWARE) from the registry.

First step

My first step would be to look at the Acrobat rendering options, especially with an older video card.

  1. My first step would be to stop the hardware rendering which you can find under Edit/Preferences/3D and Multimedia:

enter image description here

  1. You could also change the Preferred Renderer (from Directx to Software) but I'm unsure what other implications that might have - it might be overall slower, but eliminate the 'hangs'.

Next Steps - disabling unused add-ins

WP_ gave the info for this earlier so I'll just add it here from WikiHow

  1. Go to Acrobat -> Help/About Adobe Plugins
  2. From the list of Plug-ins:enter image description here
  3. Decide the plugins you need, note down the File names for those you don't: enter image description here
  4. Close Acrobat. Browse to C:\Program Files\Adobe\Acrobat 6.0\Acrobat\Plug_ins and locate the files of the extensions you don't require, move them to another folder (so you can restore if required).
  5. Running Acrobat will now not load any add-ins you have moved, this should speed up performance and possibly remove add-ins which are causing any problem.

Extra tip: Double clicking to run Acrobat while holding down Shift opens the program without loading any add-ins for that particular instance.

This looks like the hard drive sectors where the Adobe Reader has been installed has taken a hit.

Try installing Adobe Reader on a different drive and see if the same problem persists. Assuming you have lots of PC's with similar hardware specs, you can just try swapping the hard drives and see if the same problem persists.

And finally, you can try scanning the drives for bad sectors.

Thank you for your answer! I'll try but a bad drive on both machines? To be precise i've many machines on the network but those are the only ones with those specs (however i've harddrives to spare). –  eldblz Nov 27 '12 at 9:29
    
@eldblz It's not as strange as it sounds. If two hard drives are manufactured at the same time, it's very likely that both will fail at the same time (manufacturing defects, poor materials etc.). That's also why you shouldn't buy identical drives for RAID arrays. –  gronostaj Dec 14 '13 at 23:18
    
@gronostaj thank you for your reply, just a follow up: while ago i changed the HD on one PC with a spare one (different vendor), reinstalled the OS etc, nothing changed same situation. –  eldblz Dec 15 '13 at 17:35
