SwiftNetScanUpload vs Download Speed
Download moves data toward you, upload moves it away. Most cable and DSL plans are heavily asymmetric, which is why a fast connection can still fail during a video call.
Short answer
Download matters for streaming and browsing; upload matters for video calls, cloud backup, game hosting and live streaming. Aim for at least 10 Mbps upload for remote work.
