To show that I can criticize my own work as well, here I show that sustained memory bandwidth (using an approximation to the STREAM Benchmark ) is also inadequate as a single figure of metric. (It Here I assumed a particular analytical function for the amount of memory traffic as a function of cache size to scale the bandwidth time.

Just because everything works perfectly during production testing doesn’t mean that will be the case when your website is flooded with traffic.

This is a complex topic, but to borrow from a recent post , web performance expands access to information and services by reducing latency and variance across interactions in a session, with a particular focus on the tail of the distribution (P75+). Consistent performance matters just as much as low average latency.

A finely tuned database processes queries more efficiently, leading to swifter results. This reduction in latency ensures that applications and websites provide a more rapid and responsive user experience. This is more than enough so that MySQL can reorder writes to use sequential I/O during the flushing and checkpointing processes.
