This advice from Phil, as one of the creators of ACES, is not a surprise :-) But I have a question, has anyone successfully used the latest version of the full ACES suite. We had a couple of customers look at using it and decide it was far too much work. One customer used the Quick-Look facility, but I would not base much on the results from this, since it is a rather miscellaneous collection of tests. Any set of canned benchmarks is always a bit dubious. I think you usually do better to create some test cases of your own, trying to mirror your intended application as closely as possible.
