Stephan,

optmising is set to -O2 in configure.in.

  203 if test "$enable_debug" = "no"; then
  204 	if test "x$GCC" = "xyes"; then
  205 		AC_MSG_WARN(Removing debugging option!)
  206 		CFLAGS="$CFLAGS -O2 -Wall"
  207 	else
  208 		AC_MSG_WARN(Removing debugging option!)
  209 		CFLAGS="$CFLAGS"
  210 	fi

If I use "-mtune=pentium4 -O3 -msse3" instead of "-O2" (Mingw gcc 3.4.5) I do not see much speed difference.

Regards

Holger
