AFAIK Mono performs better in non-Windows platforms.

Hi, I have 'problem' with mono engine speed. I developed and compiled app on
Win7. It uses GTK# + Cairo to draw animation of 5 000 rotating lines in full
screen. I compiled it under Monodevelop with Default Runtime / Release|x86
profile.
Now if I run it from command line like this:
PerfDrawing3.exe
It runs under .Net fw 4.0 and I get 26 FPS (one frame in 38 ms).
If I run it under Mono like this:
mono PerfDrawing3.exe
I get 10 FPS (97ms per frame) => 2,5x slower!
I tried some optimization mono parameters like:
mono --optimize=all PerfDrawing3.exe
mono --optimize=simd PerfDrawing3.exe
mono --optimize=sse2 PerfDrawing3.exe
mono --llvm PerfDrawing3.exe
mono --gc=sgen PerfDrawing3.exe
...but still the same result. I tried to aot it, but without success too.
Probably it is possible only on Linux platform :-(
mono --aot=full -O=all PerfDrawing3.exe

Here is my version string:
mono -V
Mono JIT compiler version 2.10.8 (tarball)

TLS: normal
SIGSEGV: normal
Notification: Thread + polling
Architecture: x86
Disabled: none
Misc: softdebug
LLVM: supported, not enabled.
GC: Included Boehm (with typed GC and Parallel Mark)
I quite surprised that llvm is "not enabled" and GC is "Boehm". It is by
default I hope and can be changed by --llvm and --gc switches.
Well, is there anything what I missed or Mono 2.10.8 @ Win7 is 2,5x slower than
.Net Fw 4.0 VM?
