Description Telesto 2017-10-08 10:16:55 UTC
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

Yep, confirmed this with Task Manager and observing spoolsv.exe.
Does not happen with the same text in Notepad++.

Dear Telesto,

To make sure we're focusing on the bugs that affect our users today, LibreOffice QA is asking bug reporters and confirmers to retest open, confirmed bugs which have not been touched for over a year.

There have been thousands of bug fixes and commits since anyone checked on this bug report. During that time, it's possible that the bug has been fixed, or the details of the problem have changed. We'd really appreciate your help in getting confirmation that the bug is still present.

If you have time, please do the following:

Test to see if the bug is still present with the latest version of LibreOffice from https://www.libreoffice.org/download/

If the bug is present, please leave a comment that includes the information from Help - About LibreOffice.
If the bug is NOT present, please set the bug's Status field to RESOLVED-WORKSFORME and leave a comment that includes the information from Help - About LibreOffice.

Please DO NOT

Update the version field
Reply via email (please reply directly on the bug tracker)
Set the bug's Status field to RESOLVED - FIXED (this status has a particular meaning that is not 
appropriate in this case)

If you want to do more to help you can test to see if your issue is a REGRESSION. To do so:
1. Download and install oldest version of LibreOffice (usually 3.3 unless your bug pertains to a feature added after 3.3) from https://downloadarchive.documentfoundation.org/libreoffice/old/

2. Test your bug
3. Leave a comment with your results.
4a. If the bug was present with 3.3 - set version to 'inherited from OOo';
4b. If the bug was not present in 3.3 - add 'regression' to keyword

Feel free to come ask questions or to say hello in our QA chat: https://web.libera.chat/?settings=#libreoffice-qa

Thank you for helping us make LibreOffice even better for everyone!

Warm Regards,
QA Team
