The numbers Martin names (up till 10 times slower, even without linking) are the numbers I have in mind too. IMHO denial without tests is unfair. I had a setup where I compiled zeos with FPC and Delphi (which doesn't link), and iirc the results were also 7-10times, with delphi XE. When I'm home after Christmas I'll play a bit and see if I can duplicate the experiments with Delphi XE3. _______________________________________________ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-devel
