MTU controls how big each packet gets on your connection. You set it wrong and things slow down fast. I hit this issue last month on a client link that kept dropping data. Packets bounce around until they hit the limit. Then errors start showing up in logs. You check the interface settings right away. Or the whole transfer stalls without warning. I tweak those values to match the path. It fixes most hangs before they grow worse.
Your network gear enforces that size rule strictly. I learned to test it with simple pings first. Fragmentation kicks in when something exceeds the cap. Packets split into smaller pieces for the trip. You end up with extra overhead from all the reassembly work. I watched a big upload choke because of this once. The receiver struggled to put pieces back together. Or latency spikes hit during peak hours. You monitor for those signs in your tools. It saves time when you catch it early.
Admin work means spotting these patterns quick. I adjust MTU on switches to smooth traffic flow. Fragmentation adds load that builds over time. You see CPU spikes on busy servers from the extra effort. Perhaps a mis match between endpoints causes repeated splits. I trace routes to find where sizes clash. Then lower the value on your side to stop it. Partial packets float around and waste bandwidth too. You avoid that by matching settings across hops. It keeps things stable without constant fixes.
