Latency vs Bandwidth: Delay vs Capacity

Sat, 01 Aug 2026 20:14:00 +0900

Overview

Latency and bandwidth both describe network performance, but they measure completely different things: latency is how long a single piece of data takes to travel from source to destination, while bandwidth is how much data can move through the connection per second. A link can have huge bandwidth and still feel laggy, or tiny bandwidth and still respond instantly — understanding which one is limiting you determines whether the fix is a faster link or a shorter path.
