Well, I exclusively use multi core AMD x64 cpus here. I was surprised to figure out all of this a few months ago and promptly removed Win64 back to Win32 on my laptop. But I do use Ubuntu x64 everywhere else. How is it possible that under *nix I'm able to live with the memory performance of 64bit FPC but cannot with Windows? I really think that for scientific computing Linux would be better (since it's free). However, for commercial grade service applications Win64 support for FPC is essential. I was going to raise these issues a while back when I learned of this. I just figured that someone needed an MS Windows XP x64 license... Which I am willing to donate... _______________________________________________ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-devel
