      Description

      The performance of QDomDocument::save() is very slow when saving to a network drive. This is a regression from Qt 4.3.

      Preparation:
      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
