  • Due to the heated debate in comments as well as answers on this question it has NOW BEEN CLOSED. If we cannot be objective in answering a question, the question is simply degrading the standard of this site and the response from the users in this post is unacceptable by SU standards Sep 25, 2010 at 11:25
  • @Diago: This is a useful question, only the comments aren't. Why not delete all comments (including this one) and leave the question?

  • @harrymc Because even some of the answer are subjective. There is not a signal answer that gives a valid and technical reason as to why it is a suitable replacement. This is honestly the worst answers I have seen on a question on SuperUser yet. Sep 25, 2010 at 14:04
  • It's notable that one of the people voting to close is one of the people on the wrong end of the arguments. Sour grapes have no place on SU.

Foxit Reader free viewer gives the same quality of display as Acrobat Reader, but is MUCH faster.

    +1 Adobe Reader has become a bloated behemoth of an application over the last 5 years or so, and despite the many utilities available (that effectively keep the app partially loaded into memory all the time), is never going to beat a slim-line application like Foxit.

    -1 This does not answer the question! More features (which people nowadays love to call bloat, just because they don't use it and THINK it is slower) do not affect the performance of your application. Foxit Reader can't even compare to the top-notch quality rendering feature of Adobe Reader which is a required specification in the question... Sep 23, 2010 at 15:30

    1) not everyone can just use Foxit (or others). Not everyone has ability to install (Granted... this may also cause some problems with ability to fix) 2) Those who can, for compatibility reasons, may still not want to. Adobe is still, weirdly enough, the standard. Same reason IE6 won't die.

    @harrymc: The verdict was clear from the beginning, it does not answer the question on how to speed Adobe Reader up. It's the same like: "I want to keep using my i7 PC. How can I make my i7 PC even faster?" "Buy a [insert some non-quality material here that allows you do a lot less].". People want to use Adobe Reader to read there Adobe PDFs; it's like people that want to use their PC to play games that are meant for the PC, people that buy something else of a lower quality will not have the same benefit.

    @Harrymc TomWij said it... Not everyone wants to, or CAN, replace Adobe (For various reasons). The question wasn't "Can you recommend a replacement?". The question is "I like Adobe. How do I tune it?" Popularity isn't proof of a good answer.

Try the following app to see if it can do what you need. Other than that, I don't think there's much you can do.

PDF SpeedUp 2.01 (311KB, Freeware)

PDF SpeedUp allows you to significantly speed up the time it takes to load Adobe Reader. If you notice that when the Reader starts it loads many plug-ins which you may or may not need, this program simply disables the plug-ins and loads only the absolute necessary ones so the program starts quickly. It offers several options and you can also manually enable or disable the plug-ins as needed. PDF SpeedUp works with Acrobat versions 5 through 9.


Instead of "download this program that does it for you" (some people like DIY) or "use this other package" (not everyone can just install Foxit instead... not everyone wants to.)...

Look in the Adobe\Reader 9.0\Optional directory... README.TXT says:

"Put unused plug-ins in the optional directory."

So simply:

1) go to your Adobe\Reader 9.0\ folder
2) move everything from the plugins directory... into the optional directory. If you need something later, move it back.
3) ...
4) profit

While at it: Harden Adobe Reader against attacks
- disable non-essential functions, like javascript, that cause the most security issues.


Sumatra PDF, ditch Adobe Acrobat Reader, it's not worth the hassle in the long run. All the vulnerabilities, etc.

Although FoxIt Reader is good too, Sumatra PDF can't be beaten in terms of speed. In my opinion.

And no, the OPs questions does not in any way implies he/she's not open to alternatives, which is exactly what I gave.

    "How do I make my ford run faster?". "Get rid of the Ford, and drive a Chevy instead" isn't really an answer. Question implies desire to keep current product, and just make if run faster.

  • @NoCanDo: This site and question are not a place for software recommendations. Sep 23, 2010 at 20:12
  • @TomWij: WTF you mean this is not a place for software rec.? Last I checked software rec. are exactly the kind of thing SU allows. Sep 24, 2010 at 10:05
  • @TomWij - Yes this is the place for s/w recommendations - if they address the problems that the OP is facing. It is not, however, a soapbox for one particular publisher's fanboys. The SO community has spoken and they disagree with you.

  • @NoCanDo: No... I don't see how this question requests software recommendations, nor do any questions of the same type as this one. Unrelated, questions that purely ask for software recommendations tend to be too open ended and result in long lists posts rather than an objective answer. Hence, it's disallowed unless it's asked explicitly and specifically... Sep 24, 2010 at 12:27
