Understanding Bufferbloat: Why Latency Spikes Ruin Online Gaming & Video Calls

Discover why a 1 Gbps fiber connection still lags during competitive gaming and video calls when someone streams or downloads. Learn the queuing theory behind bufferbloat, how loaded latency differs from idle ping, and how Smart Queue Management (SQM) eliminates lag spikes permanently.

Idle ping only measures latency when your connection is quiet; loaded ping measures latency when data streams saturate your link.

Bufferbloat is created when routers use oversized FIFO (First-In, First-Out) memory buffers to avoid packet loss, inadvertently delaying time-critical packets.

Purchasing higher bandwidth from your ISP will not fix bufferbloat if queue management is absent at your router bottleneck.
