Yes, it's a very real effect. I got 10 seconds to render Skyvase under
Windows, and 24 seconds under Linux. The reason for this is the
different compilers used: in the Windows version, the compiler produced
several versions of parts of the code, each version optimized for a
different CPU. This gives a larger but faster binary than the Linux
compiler, which appears to have optimized for a generic x86 processor.
