memory usage pdfxchange WOW WOW is this crazy

[zfactor]

this was with one file open granted the file was about 80 pages but i mean wow...... this is nuts!!!!! this was upon opening the file... after scanning down through the whole file it was up to 1,020,xxx!!!! that is simply nuts, this same file with foxit was using a total of 33k after scanning down through the whole file...

edit wow see second pic....

[yeow]

Heh, yeh same here. If you go to Edit- Preferences- Performance- Mem Usage, you can set 10% as mem usage limit. Still more than Foxit, but system-wise it still feels ok.

Yes, memory usage is very high, and it increases when documents are scrolled. I got 850 MB peak with 3 documents (3, 106 and 53 pages) opened, it later decreased to 570 MB.

Is this a new wrinkle? I installed PDFxchange because Adobe was a hog.

Yeah, & me! *Doh!*

[funkydude]

I'll stick to the Foxit executable download, no added extras.

[Daveski17]

Well, if you want minimal there is always Sumatra!

Or try optimised version -SumatraPdfOpt from here:

Resource usage = Known Issue according to Tracker Support. Fix should be available within the next 10-14 days (again, per Support). FWIW....

There's 2.5.189 (stable) on their download page. Haven't seen what's on the changelog yet.

Abt an hour ago I downloaded & installed x64 version but turned out it was still .188.

[zfactor]

i updated and i do have 2.5.189 now memory usage is not at all much different. a 25 page doc with almost no pics even is using over 100mb of ram.. still crazy imo, sucks since i like this a lot better than foxit. but the memory usage is insane

[yeow]

If you set 10% mem usage limit, it may still be high but maybe you won't feel it if you don't look at task manager. heeee

[zfactor]

it actually crashed a system with only 2mb of ram. was using almost 1.6gb of ram before the system bsod...

[yeow]

Wow, but that should be using default setting "Automatic"? Have you already tried with 10% limit setting?

[zfactor]

okay set it to 10% opened a 24 page TEXT pdf no pics at all... uses 97mb after scrolling all the way down. foxit uses 17 for this same file. i lode pdfxchange and it renders MUCH better than foxit but its ram usage is simply insane. the newest adobe does not even use this much!!!!

[yeow]

yeah if u have 4gb ram, it may use up to 400mb (easily!). That's really alot, but I wouldn't know it unless I looked at task manager.

Are you guys using a paid version of pdfxchange or something? My latest free version is v2. build 057 and the memory use is 70Mb.

Pretty sure it has nothing to do with free or paid; the new build (builds actually) that were released over the last several days appear to present this issue.

Viewer builds: 2.5.188 and 2.5.189

Try setting it to 1% then. Just type in a "1", click "Apply" and then "OK". It works!

Just learned a little while ago that the reason for the high memory usage is caching. However, minimizing the Viewer, or just letting it sit idle for a few minutes, results in the release of all of that cached memory.

Regardless, you can set memory usage in "Performance" to anything you desire (including as low as 1% of available RAM, as I suggested above).

yes it does work but setting it to say 2% on this 2gb system makes it render pages very slowly and its pretty choppy it also must re render them as you scroll back up again

[yeow]

Great tip! Nice to know that, thanks prius04.

FWIW... I still had a PC with version 2.0.54 on it (with Performance set to Automatic) so I checked it and it used a larger than expected amount of memory too. So IMO, I don't feel that this is a totally new problem. But even with the memory issue, I can't remember ever crashing a PC on PDF-XChange. And we switched to it in our office almost 2 years ago.

I will say that now that I know I can limit the amout of RAM it uses, I plan to do so as part of my typical setup parameters. Thanks for passing along that info!
