What is Bufferbloat? (How to Audit & Fix Lag Spikes)
Bufferbloat is the silent killer of gaming performance. It occurs when other network activity (like a Netflix stream) ruins your game latency.
Audit Specification
Bufferbloat happens when your router buffers too much data, causing massive latency spikes during high network load.
Game lagging when someone else is on TikTok? You likely have bufferbloat. Test your router performance now.The Oversized Buffer Problem
Traditional routers try to prevent packet loss by saving data in a buffer. While good for video streaming, this is terrible for gaming because it adds "queue time" to your packets. Your inputs sit in a line instead of being sent immediately.
Identifying the Spike
If your ping is 15ms while idle but jumps to 200ms when you run a download speed test, you have severe bufferbloat. This is a router-level failure, not necessarily an ISP problem.
The SQM Solution
Smart Queue Management (SQM) algorithms like Cake or fq_codel intelligently prioritize small gaming packets over large, bulk transfers, keeping the "pipe" clear for your actions.
