            Bug ID: 101300
           Summary: EDITING, FILEOPEN: Slow performance and random
                    crashing
           Product: LibreOffice
           Version: 5.2.0.4 release
          Hardware: x86-64 (AMD64)
                OS: Windows (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Draw
          Assignee: libreoffice-bugs@lists.freedesktop.org
          Reporter: echarr...@hotmail.com

Just performed an upgrade from 5.1.4 to 5.2.0 on a Windows 8.1 system. I am
editing an ODG diagram that started from a Visio diagram and has about 200-300
lines/shapes on it. I had no issues with version 5.1.4, but now Draw is very
slow and randomly crashes after approx. 5-10 minutes of use with either a
crashreport, or a "Fatal error osl::Thread:create fail". Opening a file is slow
as well as simply scrolling the page. Watching the CPU usage does show the
soffice.bin using about 20% CPU and 200 MB of memory. 

Default memory settings are: 
Use for LibreOffice: 128Mb
Memory per object: 12Mb
Number of objects: 20

I have combinations of the following settings (which seem to make it slower):
Use for LibreOffice: 256, 1024, 2048Mb
Memory per object: 8, 10, 20, 40Mb
Number of objects: 5, 10, 40

Also tried disabling OpenGL and OpenCL which also seem to make it slower.

I am not having any issues with any of the other Libre applications like Writer
and Calc.
