Another Pair of Unladen Swallow Optimizations

The article describes two specific optimizations for the Unladen Swallow Python implementation. The first involves optimizing functions with a finite range of arguments (like unicode.encode), yielding a 3-6% speedup in a Django benchmark. The second discusses a JIT patch that emits optimized machine code for monomorphic operator sites (e.g., int + int) to improve performance in algorithmic workloads.
