I am curious what will happen when we run the commands in the reverse order. The LANG=C variation before the first. I suspect some of the speedup is because you just brought the file into memory.

Not only that, the search branches are sitting in the CPU caches.

Wouldn't the cache be flushed by the OS and other background processes, in the mean time, plus the display updates in the shell and the shell history?
