Kind of, in a general sense. As best as we understood it from simple profiling runs, the issue was that when NS packages are enabled, the number of filesystem calls made in path searches explodes. That's obviously always going to be a problem, but it's particularly concerning for those of us (like John and myself) who live in environments where most things are network-mounted disks (NFS, typically). Tens of thousands of path searches over the network can really cause a hit. But setuptools is complex enough that I don't want to badmouth it without a very precise analysis of the real root causes of the problems, which I don't have time for right now. I just know that using it well will require some understanding of its behavior, which is a bit 'magic' at times.
