A clean, lightweight alternative to Python's twisted? [closed]

... None of these solutions will avoid that fact that the GIL prevents CPU parallelism - they are just better ways of getting IO parallelism that you already have with threads. If you think you can do better IO, by all means pursue one of these, but if your bottleneck is in processing the resul...

Performance of Arrays vs. Lists

...e. The bounds checking is often no big deal (especially if you are on a cpu with a deep pipeline and branch prediction - the norm for most these days) but only your own profiling can tell you if that is an issue. If you are in parts of your code where you are avoiding heap allocations (good exam...

Why is SSE scalar sqrt(x) slower than rsqrt(x) * x?

...lers like clang choose not to use reciprocal + Newton for scalar on recent CPUs, because it's usually not faster. In most loops, div isn't the only operation, so total uop throughput is often the bottleneck even when there's a divps or divss. See Floating point division vs floating point multiplic...
