            Bug ID: 112991
           Summary: Printer spooler is triggered when copying text which
                    reduces the copy speed with 1/3 (for a large file)
           Product: LibreOffice
           Version: 4.4.7.2 release
          Hardware: All
                OS: Windows (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Writer
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: telesto at surfxs.nl

Description:
Printer spooler is triggered when copying text which reduces the copy speed
with 1/3

Steps to Reproduce:
1. Open the attached file
2. Open a process monitor tool
3. Select all (CTRL+A)
4. Copy (CTRL+C)
5. If the Printer Spooler service is active the process will take up 2-3% of
the CPU reducing the LibO process from 25 to 15%. Copy speed will around 66
seconds (on my system)
6 When disabling the Printer Spooler services ->  Start menu and type services
-> Disable  Printer Spooler the LibO process will steadily run at 25% (and
needs only 44 seconds)


Actual Results:  
The printer spooler is interfering with the copy process somehow

Expected Results:
Not sure if it's needed. No issue when disabling the Printer Spooler. 


Reproducible: Always

User Profile Reset: No
