Hi All, This question is related to the performance of wine using wine and WineLib I have a win32 program that uses a dll. I am checking the timing to execute a function that is exported by the dll I wanted to execute this program in Linux (using wine and WineLib) and check the performance. When I executed the win32 program in Linux using wine <win32program> The execution time of the function exported by the dll is as same as in direct execution of the program in windows Then I converted the dll into .so and compiled and linked this .so with win32 program using WineLib and Wineg++ The timing that was taken to execute the function exported by the dll ( through .so ) is almost two times, compread with executing using wine. Does any one has any reference for further investigation on this problem or any information Thank you Ajay
