P3: Somewhat important
Windows7, Windows XP
The performance of QDomDocument::save() is very slow when saving to a network drive. This is a regression from Qt 4.3.
Assign a UNC path to a network drive, e.g, \\otherpc\share to Z:\
Steps to reproduce:
1) Build the attached example.
2) Execute the example with a local path.as an argument e.g,
> sample.exe C:\Qt\outputtest
3) Execute the example with a network drive path as an argument argument, e.g,
> sample.exe Z:\outputtest
This has been tested against both Qt 4.7.1 and 4.3.5 with the following result:
4.7.1 Local 1731 ms
4.7.1 Network 30232 ms
4.3.5 Local 1778 ms
4.3.5 Network 1841 ms
