How many transactions per minute does world's biggest company need at

Ten years ago Visa could process 56,000 messages/second. It must be a
lot more now. I think a transaction is two or four messages depending
on the transaction type.

Is not this number small relatively to capabilities of
even 15 y.o. dual-Xeon server with few dozens of spinning rust disks?

Uh, no, it is not.
