I've ran this benchmark several times over the years... Cadalyst points out that it is created for vanilla AutoCAD and not for the verticals... however, I know that it runs through to completion... there are parts of it though that does not run, but fails. So I have simply modified my reporting to not consider what it doesn't run.
I think if I recall correctly that the DXFout disk access portion is the only part that doesn't run. at any rate, I am wondering if anyone has modified it to run every aspect of it on AutoCAD MEP?
