HI Antione, I can't comment on Mingw, but its that the performance difference is down to the compiler or the underlying filesystem. The compiler is mostly a special version of gcc, you'll need to look to Mingw docs on this, perhaps there are some setting to you can enable for better peformance. You could try the Intel compilers to squeeze more performance out.
Finally, the filesystem slow under Windows, on some OSG related tests we've seen a 10x difference in performance between Windows and Linux - just open an OpenFlight file on a dual boot system. Robert. On 6/10/06, Antoine Hue <[EMAIL PROTECTED]> wrote:
Hello, we are on the long way to port our application from a Linux/Mac OS X version to Windows. To simplify this port, we have tried it using MingW. We are almost at the end of the port. However, performance of the ported application is very low when it comes to generate terrains using osgTerrain. What I mean is that given a fairly recent machine (Pentium IV 3GHz, 1GB RAM), the same terrain generation under Linux is much more (no measurement but it is a few times more) faster than under Window/MingW and this even for small terrains. Are there some tweaks to the MingW or Windows to make it faster? I was thinking of making a single DLL for all osg libraries, did some of you tried that already?
