something deeper than notepad has a big performance glitch


    • Type: Bug
    • Status: Resolved
    • Priority: Major
    • Resolution: Fixed
    • Fix Version/s: 0.4.8
    • Component/s: Wine
    • Labels:


      This is a ticket (just) about execution performance, but this sucks regularly, so:

      It's broken since 0.4.0 at least (or since forever?).
      I report it against 0.4.8-dev-664-gf463ebe.
      VBox 4.3.40.

      Steps to reproduce:
      -Double-Click C:\reactos\readme.txt (or any other arbitraty txt-file)
      -It will open up properly in notepad.exe, but it will take very much time before the text is actually rendered to completion (slowness)

      Only thing that is logged then, is

      fixme:(../dll/win32/shell32/shlexec.cpp:1804) flags ignored: 0x00000004
      CFSFolder.cpp:735: Unexpected failure 80004002.
      CDrivesFolder.cpp:506: Unexpected failure 80004002.
      CRegFolder.cpp:422: Unexpected failure 80004002.

      But the logging is not the reason for the slowdown.

      I verified (all tests done in same virtualization):
      -our notepad run in W2K3_SP2 is fast
      -W2K3_SP2-notepad run on W2K3_SP2 is fast
      -W2K3_SP2-notepad run on ros is slow
      -our notepad run on ros is slow

      I conclude: It is not our notepad-binary that sucks, but either text-rendering, scroll-bar-rendering or file-IO that is slow.
      I suspect it may be related to the scrollbars.
      Eventually related: CORE-13631 or CORE-11561.
