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 Mono Ahead of Time compiler - compiling assembly PerfDrawing3.exe Code: 23432 Info: 461 Ex Info: 1466 Unwind Info: 103 Class Info: 1041 PLT: 167 G OT Info: 1756 GOT: 936 Offsets: 1330 Executing the native assembler: as -o \AppData\Local\Temp\mono_ aot_a06524.o \AppData\Local\Temp\mono_aot_a06524 'as' is not recognized as an internal or external command, operable program or batch file. AOT of image PerfDrawing3.exe failed. Here is my version string:
>mono -V Mono JIT compiler version 2.10.8 (tarball) Copyright (C) 2002-2011 Novell, Inc, Xamarin, Inc and Contributors. www.mono-pro ject.com 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? _______________________________________________ Mono-list maillist - [email protected] http://lists.ximian.com/mailman/listinfo/mono-list
