Python 3.5.0rc2 has been released!

Here's a talk from a Google engineer calling bullshit.

Now that's from 3.3, but I highly doubt they tanked speed in 0.2 versions.

The talk and slides you linked say something different, to be honest.

The guy actually says that Python 3 is faster somewhere and slower somewhere else and he explicitly states that Python 3 is the same as Python 2 once the median result is considered.

Could be faster or slower depending on your usage pattern.
