AcroRd32.exe high CPU Usage

Hi,

I am running Reader X on a  2008 terminal server.  Any time a user opens a PDF document the process AcroRd32.exe starts however doesn't close when the user closes the PDF document, the process also has high CPU usage of 25% per document opened.  So after a short while the cpu is maxed out and the server becomes slow and unresponsive.  I have downgraded to Reader 9.2 as a short term fix.

Is there any fix for this?

We have found that the information bubbles that open up in the top right hand corner of pdf documents can consume a lot of CPU, when visible for a user on our RDS servers Acrobat Reader would consume anything between 14-25% of CPU resource. This turned out to be very easy to resolve - first you can simply close the info bubble as the user, this setting is then retained for the next time any pdf documents are open. However this was not a suitable fix for the several hundred users that we have regularly connected to our various RDS farms. Instead we added the following registry settings to each users profile via our logon scripts - these disable the info bubbles and therefore prevent the high CPU usage.

KEY = HKEY_CURRENT_USER\Software\Adobe\Acrobat Reader\11.0\AVGeneral

DWORD = bReaderShouldShowInfoBubble

VALUE = 0

DWORD = bReaderShowEPDFToolsPaneInfoBubble

VALUE = 0

I hope that this information helps other users with similar High CPU issues when running Acrobat Reader.

Hi Guys,

there is another thread about this same issue. I think it would help if we all voiced our concerns about this issue in one place.

Hi, the same probleme here with w2k3, Citrix Presentation Server 4.5 and Acrobat Reader 9.3.3.

Every AcroRd32.exe process (with or without open PDF) takes 13% (on a 2 QuadCore Processor Server). No problem/load when opened as an Administrator. Could this be a missing right?

Cheers, Andy
