Hmmm, I guess so.

OK, if you say so…
I thought that using gcc to build the program on Mac OS X as well as in the VM will lead to comparable code, but I understand from what you wrote that this is not necessarily the case. :-(

Looks like it.

The more shocking stuff I have is MacOSX's version of aqbanking being 2-3 times slower than the Linux counterpart.
This might be due to some network access which obviously seems to be that much throttled under MacOSX. Wondering which tools to use to figure out where the bottleneck is. But from aqbanking's output I do see already that it slows down during communication with the remote banking server…
I guess I'll have to contact aqbanking's mailing list for more help.
