title="NEW - Bump in CPU usage when deleting a bullet row"
href="show_bug.cgi?id=113091">bug 113091</a> (based on <a href="show_bug.cgi?id=114012#c5">comment 5</a>). The CPU usage is pretty high for
deleting some content with backspace.
This is about the small bump (of around 5%).
Steps to Reproduce:
1. Open <span class=""><a href="http://bugs.documentfoundation.org/attachment.cgi?id=137565" name="attach_137565" title="Example file">attachment 137565</a> <a href="http://bugs.documentfoundation.org/attachment.cgi?id=137565&action=edit" title="Example file">[details]</a></span> file based on <a class="bz_bug_link
bz_status_NEW "
title="NEW - undo/delete consumes much cpu power and is slow in large documents"
href="show_bug.cgi?id=113067">bug 113067</a>
2. Place the cursor and the end of the latest word on the first page
3. Hold backspace and monitor CPU usage
Actual Results:
A bump in CPU usage from 20% (LibO5.0) to 25% (since 5.1)
Expected Results:
Should be less CPU intensive
