Is there a performance comparison of different IVF versions

Is there a performance comparison available of different IVF versions?  It would be great to know that newer versions should perform better, or at least not worse.

In very hasty comparisons between 13.0 and 19.1, I'm finding 19.1 significantly slower.  I hope that's my fault and not the compiler version.

One of the release criteria is that the new version not perform worse than the previous one, on a series of standard benchmarks. Individual applications may vary, however. In my experience, new versions generally perform better.

Excellent, thanks.  That tells me where to focus efforts on finding what's affecting execution times.
