There is of course the ACVC suite, which is quite comprehensive.
But from our point of view the critical test suites are the ACT
internal regression suite (5500 directories of test cases with
many millions of lines of code), and the DEC test suite. Both
these suites contain highly proprietary customer code, and
cannot be released publicly.

Probably a good thing, but see below

Now you seem to be back in the mode of wanting the latest and
greatest even if it is not tested fully. Personally my reaction
to a 5% gain in speed for one program is that this is not
interesting enough to jump the gun and try to put together
software components that have not been designed to work with
one another and have not been tested.

But by all means go ahead, and definitely let others know your
experience. The pioneers can always help those who follow later :-)
