Re: [Mingw-msys] Slow performance of msys+mingw built program when run in win32 console....

[Chung-Lin T. <u88...@cc...>]

Win2k, and the only console output is a single line printing the elapsed 
rendering time,
and no, minimizing the console doesn't help....

To elaborate more, when linked with the SDLmain with stdio redirection 
(to stdout.txt, etc.),
the performance returns to about 6 sec in the Win32 console, except the 
redirected stdout.txt
file shows up as a 678KB file filled with blanks, and my single line of 
message at the very bottom
(This could be SDL's problem, I don't know...)

The slow performance happens when linked as a normal console app 
(WITHOUT stdio redirection,
and no -mwindows); I switched the display backend code to use another 
library(TinyPTC) to test,
and the performance was still about 22 sec, so I think this is a 
MinGW/MSYS problem ......
 
Thanks.....
