Allocate more memory for Acrobat

[Jean-Pierre5C9A]

I have 32 GB of RAM. When I open 3 very large PDF files (about 1000 pages), one of which includes a comparison, the system becomes very slow. I see that Acrobat doesn't seem to use much ram. How can I allocate more memory for Acrobat DC?

I don't believe you can do that yourself.

Thank you very much for your reply.

Would it be possible for you to forward this suggestion to the product manager please?

Recent computers often have 32 GB of RAM. I guess that this would go along with making it a 64 bit software (I just read that it could be 32 bits, but I didn't check myself).

Have a very good day.

No. I don't work for Adobe. You can make a feature request here:

Thank you. I did. Anyone who wants to support this idea can do so. The title of my suggestion is :

In which operating system is Acrobat on?

Depending on the OS, there may be a few tweaks that you can experiment with at the OS level.

What version of Acrobat? Like 2016.124.98765

[Jean-Pierre5C9A]

I have a subscription to Creative Cloud, and everything is up to date.

More precisely, Adobe Acrobat Pro DC, continuous release, version 2021.011.20039.

Hi, I'm having the same problem. Thank you for raising this issue.
I am an academician working at a university. I spend all day working with PDFs. However, Adobe Reader tires me more and more every day. Adobe is slowing down my work. I use 24 GB RAM but Adobe reader constantly freezes. It crashes constantly. I'm tired now. I have an Adobe membership and everything is up to date, but I feel like I'm in 2005 when using Adobe reader. What I understand is that Adobe engineers never read books, never do research, never use Adobe Reader / DC. Since they don't use it, they have no idea how this program is supposed to work. They just write code and go home in the evening.

I have no idea of the accuracy of your inside info about the Adobe engineers, but if that's true that they

execute the writing of their software platform inside some kind of bubble of ignorance and are additionaly that out of touch with the end users of their product (which are millions upon millions), then that if very disheartening.   Their marketing strategy from the outset was top touch though.  I gotta hand it to them for how they distributed their software for "free (yay!)" in the early years to get businesses all over the world to accept and proliferate their software on a global level.  And then years later they cashed in on the world wide acceptance their software.  That was genius forward thinking strategy.

By the way, I have a 32GB ram rig with a fairly fast CPU.  The CPU is not as up to date as it could be but the RAM is adiquate I think.  I'm having the same problem of progressivly slower and slower response while editing a 12,000 page repair manual.  Running Window 10.  I found out how to flush the RAM cache on demand and created a shortcut for the action on my desktop and also one to clear the clipboard but it doesn't seem to help.  Apparently the undo saves are either not kept in the RAM cache or are not "allowed" to be wiped from the RAM cache.

I very much wish I could select to allocate more memory to adobe while using it.  The program starts piling up undo save data from the moment you start editing a document.  The undo saves are a life saver and even when Adobe crashes all those saves are kept separate so that when you reboot the program you can choose to save all your progress up till the crash.  Very nice that is.  It just needs more memory allocation.  So far my only solution, when I notice that simple actions start getting slowed down to a certain level,  is that I have to Save, close out the program, then reopen Adobe and my document for fresh start.  All those undo saves get wiped from memory and that's the only thing that unbogs it.

By @Nucklehead

If the Undo cache needs to save you in the case of a crash, they need to be saved to the disk, and not kept in memory.

That is very commonly a solution to many computer problems. I do not have 12,000 pages repair manuals, but it sounds a bit crazy to me to keep that all in one single file. In addition, I would edit the source file, not the print file.

[Nucklehead]

Thanks for the reply.  I'm not a software tech so I was just guessing where the undo saves were being kept.  Thanks for the info.

About the file size of the manual, it's an automobile shop repair manual and all that info need to be conveniently kept in one file for easy cross-referencing from one section to another.  I wish it was at least half that size but it's not.  I'm not the author or that manual.  I'm just fixing massive formating issues with readability and printability.  I don't know what program they wrote the manual in but when they exported it as a .pdf the layout formatting got all screwed up.  If they had written the thing in Acrobat to begin with I'm sure it would all be right.
