Because web devs are so used to terrible design, poorly-optimized DB schemas, and networked storage latency that they have no idea what a single server (or indeed, a humdrum desktop) is capable of.
Like when I inform teams complaining of “slow queries” that the DB is executing them in sub-msec time. No idea what the rest of your stack is doing, but good luck with figuring that out - it ain’t me.
