Acrobat X Pro: Really slow opening files

[lenahanson]

Since the last upgrade (I got it last week a couple of days after I installed the program), it takes forever sometimes to open the simplest files. Up to 10 seconds to open a one-page file. More if the file is larger. This is really annoying, as I am opening files all the time. It doesn't help if I close the program after each file is printed, or leave it open and just closing the file. Anybody else experiencing this who knows what's happening?

Version 10.1.0.534

To fix the load delay.. remove any non functioning or slow Rights Management Servers from Security Settings. Document open triggers UI items to get enabled, which fetches the set of policies that you can apply on a document, and show them within the menu. Somehow this seems to happen each time a document is opened.

YES i have the same problem but worse - sometimes it's says the wow cache or stack and slows down everything else I have going on. I want to know how to return to the previous version.

I had the same problem -- extremely frustrating -- but I found a solution that works for me.

Open up a pdf file, go to Edit, then click on Preferences in the pull-down. On the left, near the bottom, click on Security, then unclick the box near the top that says "verify signatures when the document is opened".   Now all my pdf files open quickly, as they used to!  I have no idea what this verify signatures thing is for but I'm ok without it.

Thanks but Actually I had already done that and also unchecked the enable enhanced security. Perhaps it did improve it somewhat but still is slower and more problem to use than prior version(s).Besides being too slow it seems usually to even open a 2nd or higher file when I push enter it does nothing and have to keep on pushing enter till it finally does it or messes up things so much I need to reboot or something - same thing with rt. clicking and going to open with adobe it ignores my command more often than not esp. when have other applications open whereas prior versions did not have this problem.

I'm not sure if this has anything to do with it but....   having just checked my 'reliability monitor' (via control panel) - there is an warning mark right next to Acrobat X Pro with the message 'Unsuccessfil application reconfiguration'. I haven't asked Acrobat to do anything today so what ever the error is, it's done it off it's own back. (As you'll see from previous notes, i too am having issue's since the update. Using Windows 7 Ultimate SP1)

Same here - Slow opening pdf-files (approx 10-25 seconds)

[Bill12]

After all the discussion, I can't resist adding a little dig in the sense that your file are slow to open like the display in this forum. (OK, this goes way back to when the forum was changed over and the analogy is something I just could not resist!) Sorry for wasting space in this topic.

[Guest]

Same problem as both in XP SP3 and WIn7 SP1. I reinstall acrobat x to 10.0.0 and problem disappered. After updating, it begins to open second file very slow.

Need fix ASAP!!!

[lenahanson]

No solution to this problem yet? It's been months!!! Has anybody been in contact with Adobe? We can't be the only people on this earth with this problem!! My hair is getting grayer by each day and my ulcer is growing...

Wish this work.

I installed the pitstop plugin. After diabling that plugin, the world became Nice Again.

Good luck to all~

My Acrobat recently got updated to version 10.1.1 and now it opens pdf files without any delay. I would suggest all of you facing this problem to update your Acrobat to latest version (10.1.1) as soon as possible.

The update seems to have really sped things up. Good job, Adobe. Hopefully I'm not speaking too soon.

Regarding the ridiculously slow opening of PDF's in IE8 web browser (I know not OP's problem), it is still ridiculously slow with Acrobat 10.1.1 and Reader 10.1.1 installed.

If I uninstall Acrobat X and leave Reader (10.1.1) installed they open damn near instantaneously in IE.

Install Acrobat 10.1.0, PDF's can take up to 60 seconds before viewable.

Update to Acrobat 10.1.1, PDF's can take up to 60 seconds before viewable

Turn off all the addins in browser, no change.

Any definite fixes for this anyone .. please? Preferably one I can recommend to external clients as well as they are having the same issue viewing the PDF's off our website.

[lenahanson · Accepted solution]

All my problems disappeared after the last update (10.1.1). All files open quickly!

[OzVic]

That's in the browser lenahanson?

I just downgraded Acrobat to 10.0.0 and it's instantaneous again (Reader 10.1.1). Can't really tell customers to do that though .. damn.

[lenahanson]

No, I always open my pdf:s in a separate program window.

[Guest]

The problem for me also went away when I updated to v10.1.1. (for WinXP)

The problem is mostly about having thumbnail views applied to your folders and the setting (in XP) "show common operations in the same folder".

If I turned that feature off, the problem went away (with the previous version).

I can still sense some delay in opening of PDFs, with the new version, but nothing like before.

[Dougefresh091]

This may not be the answer you want to hear, but I'd suggest using a different browser. That's just my opinion as I hate IE... Chrome is excellent, IMO: http://www.google.com/chrome

[OzVic]

Yeah, I use Chrome myself and the builtin PDF viewer is instantaneous. Can't really tell our clients who work at hospitals etc to change their browser though (IT won't let them), or to turn off "Display in browser" in their Acrobat settings, or to right-click and save as.. to speed things up.

Would be better if Adobe could just tell us where the problem lies or even better .. fix it.

I have not seen anyone post full test results, so here is my testing:

Windows 7 x64
Internet Explorer 8

Adobe Acrobat X Pro

10.0.0 - Works
10.0.1 - Works
10.0.2 - Works
10.0.3 - Works
10.1.0 - Slow to load PDF Forms inside browser
10.1.1 - Slow to load PDF Forms inside browser

I have not found any Adobe Acrobat Preferences that will fix this either.

[OzVic]

Exact same setup in out org nzorn and exact same results.

Is Adobe going to fix this? I can't log a support case as don't have support details.

[OzVic]

Hey nzorn, maybe you can verify this for me:

When I RDP into computer it works instantly (ie. normally). If I'm sitting in front of it or VNC/DameWared it is ridiculously slow (can be over a minute). This made me think it is something to do with the video driver (god knows why, Adobe you're a champ. /sarc).

Updated driver to latest version (ATI Radeon HD2400XT), no luck. Used the onboard video (Intel Q45/Q43 Express Chipset), no luck.

DISABLED the driver (so computer reverts to stock VGA), PDF's load instantly! Enable the driver, back to square one.

ATI and Intel can't be blamed because 1. It works pre 10.1 and 2. They are totally different companies.

Please somebody from Adobe read this and fix this! We run breast cancer trials as a subsidiary for a University (VLK license) but don't have support logon details where we're situated. Surely it's more than just us and nzorn with this issue!

[nzorn]

I can do some more testing when I have some free time.  I am going live with Adobe Acrobat Pro 10.0.3 since it's working fine. 

In the meantime I have filled out a bug report, but maybe others can do the same thing:  https://www.adobe.com/cfusion/mmform/index.cfm?name=wishform

I'm using 6 cores and 12G ram, but this makes no difference: the first opening the document in Acrobat Pro is terribly slow. The bug is definitely in the cashing system. Acrobat has to read the whole file before you can access it. If you close a file and open it again Acrobat makes it instantly, because the file is in the cach already. Let's wait while the new caching process will be moved to background.

But   l u c k i l y,   free Adobe Reader doesn't consist the feature (yet  :)). So you can install both applications in your system and read the documents quickly. Alternatively, one can move back to Acrobat 9.4.6, which was released the same day as the 10.1.1 (9/13/2011)

Upd:

But the most important. It seems, that installing Adobe Reader changes the overall Adobe system behaviour. And now my Acrobat Pro 10.1.1 works OK and opens large files without any delay.

Check, whether this solution suits you.

I solved the issue for myself by disabling the "preflight" plugins by moving the 3 files from the acrobat plugins folder (Preflight.api, Preflight.deu, Preflight.fra).  More details about this can be found here:  http://forums.adobe.com/message/3791427#3791427.

Not saying this is a solution, as I believe this to be a bug, but at least files are opening at the same speed as they were before this update. 

*Also, after testing (once files were moved), I put them back in the folder, and even restarted, and it's still fast.
