As you are one of the few able to measure and compare Chens products, giving the times for good ol' vfp on same HW would be helpful to all...
If Chen's error fixes introduced marked slowdown somewhere, such info is also helpful and might make it easier for Chen to find areas to polish a bit -
even if main benefit for you is moving to 64OS and/or eliminating one of the few vfp gotchas.

thx
