PyPy 1.7 Widens the Performance “Sweet Spot”

“The PyPy development team has released version 1.7 of its ‘very compliant’ Python interpreter with integrated tracing just-in-time compiler. The developers say that the focus of the new update was widening the range of code that PyPy can speed up, which the developers refer to as the ‘sweet spot’. In their benchmarks, PyPy 1.7 performs approximately 30 per cent faster than 1.6 and ‘up to 20 times faster on some benchmarks’.”
