Comment list takes too long to load

Getting comment list to show in Acrobat DC takes way too much time. It's a drag. At least on Mac OS.

    It takes over 30 seconds to open the comment panel, regardless of the number of comments or the size of the document. This has been an issue for a long time. A fresh install doesn't seem to help.

    Clicking on the comments list (only 4 in this document) is a 10-15 second delay, plus 5 seconds of beach ball and then I see the comments. This is such a slow down in production and very annoying.

    I have been aggravated by this issue for at least a year. I need to open multiple documents and view comments and each time it is an agony of waiting. I tried clean installing Acrobat to no avail. I then found some comments8 (I don’t remember if it was here or elsewhere) and they were correct. If you log out of your account and then into a guest account and open Acrobat, the comments open immediately. Go back to your own account and slow as molasses again. According to the commenter, this is an issue related to the user’s identity info on the Mac. I don’t have the slightest idea where I would even find that to change it. But the fact that comments open immediately in the same docs on a PC seems to support this theory.

    Little update on my situation. Got a brand new install on a new Mac Pro. Just Adobe CC installed. My previous computer went through several versions of Adobe products. Now everything runs normally as far as comments loading goes. If that can help troubleshooting the issue.

    I would like to add my experience. The comments list loads fine, but there is a serious drag when scrolling through and marking it. It adds to the time needed to make edits and is very frustrating. I have noticed that my Adobe Bridge has a similar drag when scrolling through photos.

    Adobe Acrobat Pro DC, fresh install 2018, cannot get the comment in the pdf to select (will not open when I double click on it) and since it will not select, it doesn't sync up with the comments panel, and bring that page's comment within view, it lags way behind. 711 pg pdf, 971 comments, 19.89 MB. XI worked fine. PDF is saved to desktop, location is trusted. Worked fine yesterday on XI Pro.

    Acrobat 2017 Standard perpetual - 900 comments. Loads extremely slow on a Dell E6540 with 8 GB of RAM and with at least 4-5 other applications opened that are required for the user's job.

    Works perfect with Acrobat XI Standard, mainly because the Comments tool does not keep re-loading like it does with the 2017 version. We have applied the latest updates to Acrobat 2017 Std perpet., but does not fix the issue. Thank you.

    I am having extremely long load times. The worst part is if I am working off the network. Once I log into my Companies network, every file I open afterward loads slow. Even if I am opening from my email or desktop. The files i am opening are usually 5MB or smaller and only 1 or 2 pages.

    It's currently unusable for me.

    Admittedly it's a big document (1750 pages, ~1360 comments), but it hangs for 10s of minutes. High Sierra, latest acrobat DC, MacBook Pro 13 with touch bar. Lots of memory and SSD.

  • Jane commented  ·   ·  Flag as inappropriate

    Yes, there is a lag, but for me it's 2 seconds on my laptop with High Sierra. I haven't checked my old or new iMacs, as I am not home.

    For me, it takes 30 seconds to open the comment panel, even if a document has no comments. Doesn't matter which document or the size of the document. Has been happening for a long time and the lag does seem to be getting longer.

    Ah! The age of the installation makes sense! The only time my comments pane was snappy was when I was recording an Acrobat course at Lynda. The comments pane opened instantaneously! I thought it was perhaps because of their crazy fast computer. But now that I think bout it, that Acrobat installation was probably done just a couple of days before I used it.

    As all others have said. Open any PDF document that contains comments. Click the 'Comments' button to open up the pane. Wait. Everyone in our office has experienced this issue since the beginning of Acrobat DC. On newer SSD Macs it's more bearable, about 3-4 seconds wait. On our older Macs with spinning hard drives it takes as long as 30 seconds for the comments panel to open. For some reason the delay seems to get longer and longer as the installation of Acrobat ages, meaning if I completely uninstall it and reinstall the app, the first few uses are pretty quick and then it gradually gets slower.

    Comment pane takes too long to load. Our whole company struggles with this...what is the fix?

  • Dave J commented  ·   ·  Flag as inappropriate

    Any pdf, any size with comments or no comments takes a extremely long time to open the comment window. It's been like this for a few years. Deleted prefs and relaunched Acrobat DC. No improvement. Still the same. Currently running El Capitan, 10.11.6 on a Mac Pro 3,1.

    I too have the same problem. It doesn't matter if it's just 1 comment or 100+ comments, it is painfully slow to open the Comments pane once it has been clicked. It should be instant but right now it takes between 15 to 30 seconds to open – on any PDF. The PDFs aren't large in size too, less the 1MB, comprised of all vector artwork and text.

    Please fix this.

    Hi Arvind,

    I'm afraid I can't send you the PDF. It's an unpublished proof of a book that's in production, and as such is confidential.

    However, this issue affects all PDFs with large numbers of comments (over around 1500), so it isn't just one particular document.

    I have the same problem. I'm on a PC, using the latst version of Acrobat Pro DC (I have tried checking for updates, but none are available) on Windows 10 (also up to date).

    I am working on a PDF of around 63MB, with around 2000 comments. I can view the document fine, but as soon as I open the comments pane the whole thing slows down to an unusably slow speed. It takes over 10 seconds to do anything at all, whether or not it's directly related to the comments. Even scrolling from one page to another takes over 10 seconds.
    As I'm a freelance editor using Adobe to edit proofs, this is a serious problem. Please help!

  • Kelly Vaughn commented  ·   ·  Flag as inappropriate

    Each time I click on the Comments list, Action wizard, or any other tool, it takes 3-5 seconds to load. I am also on Mac OS. Loading the Comments pane took 4 seconds, and I only had four comments.
