- cpeterso 10y agoAlso, CPU tasks like authenticating a message are cheap to scale horizontally. A cache is a centralized bottleneck.
- carterehsmith 10y agoThat depends on where your cache is. If your cache is on a separate box and you have to make a network round trip, yeah it is expensive. But if your cache is in-process, the access is cheap.
