Just Compiled Application Takes LONG TIME to execute in Windows , but not in Linux

[shahalpk]

a just compiled application takes a long time to execute in windows, but this behaviour is not seen in linux. also, a application which has already executed once, does not show this behavious until it is compiled again.

I'd guess your antivirus software scans the binary before it is first executed or the system decompresses the binary on a compressed filesystem. Or something like that. Anyway Qt has nothing to do with executing your application.

is it the same problem as described in this thread (http://www.qtcentre.org/threads/31549-QT-4.6.3-regression-Dll-s-under-Windows-load-slow-compared-to-Qt-4.6.2) ?
