Some of us have little money or optimized for something else. I spent a good chunk of this and last year with hardly any groceries. So, even $30 a month in hosting and CDN costs was large. Another situation is an expensive resource. This might be bandwidth hogs, CPU heavy, or higher licensing per CPU's in databases. Some people's sites or services dont scale well or hit their budget limits fast. In a high-security setup, those boxes usually have limited performance. It comes from the runtime checks, context switches, or embedded/soft processors. If no timing channels, one might have to disable shared caches, too. Those systems run slow enough that whatever is in front usually needs to throttle the traffic. We'd want no wasted traffic given their cost ranges from $2,000 / chip (FPGA) to six digits a system (eg XTS-500 w/ STOP OS). One could say the same if it was a custom or open-source chip, like Plasma MIPS. Many people might be in the poor category. A significant number are in the low-scalability category. The others are rare but significant.
