Pyston, an alternate runtime for Python

The video discusses Piston, an alternate Python runtime aimed at speeding up Python programs without code changes. Initially developed at Dropbox, Piston uses just-in-time compilation like PyPy but retains Python's original codebase. The video compares Piston, C Python, and PyPy in terms of startup times and performance benchmarks. While PyPy offers significant speed improvements, Piston provides moderate gains with faster startup, making it suitable for short-running applications. The video also highlights the limitations of runtime optimizations in disk IO-dependent tasks.
