Passed it is enough much time, but answer has not followed. The Problem

I try to state my version of the slow work WinForm exhibits in Linux in
comparison with Windows. The Graphic operations in WinForm exhibits are
produced through GDI+. Library gdiplus.dll is used In Windows herewith. In
Linux developers Mono for this have written the library libgdiplus.so, which
realizes the graphic conclusion with use the library Cairo. Cairo in Linux
can ывводить through Xlib or through Glitz (with use OpenGL). However for
WinForm exhibits conclusion is produced through Xlib. Xlib in turn is not
used hardware speedup and removes much slowly. As result to graphic
operations in WinForm exhibits in Linux on order slowly, than in Windows.

In addition to the first test (with ZedGraph) attach example of one more
test, in which ZedGraph is not used. However velocity of the work of this
test in Linux much slowly, than in Windows.
Here is results for my PC:
1. WinXP SP2 (mono 2.4.2): 13 sek.
2. OpenSUSE 11.1 i586 (KDE, mono 2.4.2): 76 sek.

Cod:  http://www.nabble.com/file/p24548408/test1.zip test1.zip 

As possible accelerate work WinForm exhibits in Linux? Plans Novell to use
the hardware speedup graphs for WinForm exhibits?

Thanks! Igor.
