> An enourmous amount of time spent profiling, benchmarking and optimizing things. The answer is different for every part of Bun, but one general theme: Zig's low-level control over memory and lack of hidden control flow makes it much simpler to write fast software.
With modern hardware, accessing memory efficiently is key to writing fast software. Programs written in programming languages that don't let the developer control how data is laid out in memory usually face an uphill battle to be fast.
