I’m confused

Excessive memory usage.

Edit Subject

The same PDF opened in both SumatraPDF (the current Netbook favourite) and NitroPDF Reader. Note the high memory usage. Why does NitoPDF Reader need four times as much memory to open the same file?

When the mouse pointer is clicked and held in a page, the cpu utilization reaches 100% and does not go down until the mouse button is released.

Memory consumption rises proportional if document has several pages and is scrolled page by page. It seems everything once visible on screen is kept in systems memory and not released. This behaviour cannot be observed with Adobe Reader (V7.x)
For me, as an user of an slow XP PC a "No Go!" since swap file increases dramatically and PC cannot be used anymore!
I'm using the most current version of Nitro PDF.

Is anything being done about this memory issue? It is horrible. Open up a file and try to search and the Mem Usage jumps to 900MB!!, effectively disabling my computer by taking all the available memory.

  Hi Cornellus,
  
  Can I confirm how many files you have open and there sizes?
  
  Id like to look into this more with you, can you advise me what you were doing to reach this level of utilisation ?
  
  Many thanks,

  Only one file – the file is here – (if you want to download it) 118MB.
  
  http://catalogue.tjmecommerce.com/res...
  
  My one PC has 4GB memory and I can see in Task Manager it starts to have a problem when the free memory runs out at about 1.2GB.
  
  Just tried it on my i7 with 6GB (64bit Windows 7) system and it looks like the 1.2GB is the magic number where it gets stuck. Once it reaches 1.2GB I cannot even scroll the pages - it is blank.
  
  Maybe it is best if you try - Acrobat uses about 521MB and is heaps faster and loads the whole file.
  
  You can test by opening the the pages view on the left side and scroll down - it loads about 66 pages. For fun I loaded the file in both programs at the same time - Nitro still gets stuck on roughly 1.2GB and Adobe keeps on working with 521MB.
  
  I use Nitro quite a lot for the editing feature and would like to use it as the primary PDF program.
  
  Regards,
  Cornelius

  Unfortunately I can't because it's a confidential document. The issue seems to be lack of memory with the program.

Updated to Nitro 2.3.1.2 and now it will not print pdf's.
Are there any patches/fixes out there.
Running xp
When I try to print, the docs in the print tab are excessivley large and the spoolsv.exe is taking up at least 50% of cpu.
Docs are only 3page forms I have been using for years with no problems. Seemed to occur with the latest update.
Thanks,
Ken

Last week, I upgraded to latest Nitro Reader version (after checking for updates) and have not been able to print PDFs from Nitro to my Kyocera FS-1320D since (due to "excessive memory" problems) - and it also messes up any other PDF software (according to our IT professionals), not to mention stalling the printer. (To use my computer & printer, I need to reset the printer and computer - and not use Nitro Reader to print.)

More details:

Nitro PDF (R) Reader 2.3.1.2
Windows 7 Professional 6.1 7600

System memory: 1.99 GB

Any advice? (There are other PDF readers out there, but Nitro is my favorite, and I recommend it to everyone. I'd like to keep using it, but my IT Dept is going to make me uninstall it if it's messing up the printer.)

Thanks!
