Until we can design a more long-term solution (and that’s assuming we can at all) that can asynchronously load the file, I wanted to work out a way to minimise its impact. This means that from a cold-cache, if a user were to land on this page for the first time, they’re absolutely going to take a performance hit—there’s just no way around it.

Because microprocessors are so fast, computer architecture design has evolved towards adding various levels of caching between compute units and the main memory, in order to hide the latency of bringing the bits to the brains. This avoids thrashing caches too much for B and evens out the pressure on the L3 caches of the machine.
