MCP latency test: default proxy hits 3,340ms at 8 tabs, server provider stays at 0ms

Daniel Lockyer shares a performance tip: the best optimization is not doing work you don't need. Benchmark data shows that as open tabs grow from 2 to 8, latency through the default proxy provider balloons from 148ms to 3,340ms, while hitting the server provider directly stays at 0ms regardless of load. Takeaway: the proxy layer is the bottleneck in multi-tab/multi-session setups — going direct eliminates the overhead entirely.
