Python 2 and Python 3 have completely independent installations, so it could be a lot of things. First question: Does it take three seconds *every* time you type 'python', or only the first time? If it's slow the first time but then fast, it's probably just a matter of disk caching; running Python 3 doesn't pre-cache the files for Python 2, so you have to pay the load-time cost anew. If it's slow every time, though, you may have something messing with your startup. Try "python -S" and "python -E" see if they're just as slow. That would be a way to delve into things a bit.
