...ngle-threaded environment. So it's great at dispatching but not so good at CPU-intensive processing. To cover that ground you can fork off another process/thread that runs native C/C++ code. If all you're doing is async IO calls (ex IPC | bi-directional pipes) then node.js should be able to handle t...
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...
