@irexta Agreed — a lot of teams treat bandwidth and transfer as the same thing until concurrency spikes expose the difference. For web apps we usually think about it as architecture first: app/db/cache locality, CDN offload, and then whether the uplink still holds up under burst traffic. Curious where you most often see the bottleneck first in real deployments: uplink saturation, storage IO, or noisy-neighbor effects on shared infra?
