For all we know, some of the tested apps have hand-written assembly optimisations for armv5/6 too. That would easily speed things up by a factor of 2 or more even if no floating-point is used. There are so many variables here, most of them unknown, that saying anything beyond "it got a bit faster" is pure speculation at best. -- Mans Rullgard / mru _______________________________________________ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev
