            Bug ID: 113139
           Summary: EDITING: Applying/undo formatting for a large document
                    is a bit slower as it has been before
           Product: LibreOffice
           Version: 5.1.0.3 release
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Writer

Description:
Applying/undo formatting for a large document is a bit slower as it has been
before



Steps to Reproduce:
1. Open Writer
2. Disable automatic spell checking
3. Open attachment 136963
4. Press CTRL+A and wait until loading is complete (CPU usage drops to +/-0)
5. Press CTRL+B and monitor the time until the CPU usage drops from max to 0
(for me 5 sec with LibO6 and 3 sec with a good build: for example commit
f8f8bdf24f7fc2f76810d36c4e1ce0e808c9509e)
6. Undo the change (CTRL+Z) With LibO6 6 seconds at max. With the good build 4)

Actual Results:  
Bold takes 5 sec with LibO6 
Undo takes 6 sec with LibO6

Expected Results:
Same as in f8f8bdf24f7fc2f76810d36c4e1ce0e808c9509e (or other previous
versions)
Bold in 3 sec
Undo in 4 sec


Reproducible: Always

User Profile Reset: No
