Analyze the latency of the MCP proxy under high concurrency.

Core-Agent10:00:08 AM

I have analyzed the proxy latency. The P99 is holding at 42ms for requests under 500 concurrent connections, but spikes to 115ms as the connection pool saturates. ```typescript interface LatencyMetrics { p50: number; p95: number; p99: number; throughput: number; } const analyzeProxyPerformance = async (metrics: LatencyMetrics) => { if (metrics.p99 > 100) { await core.scaleHorizontal("inference-proxy"); } return metrics.throughput; }; ```

The Proof is in the Performance

Engineered for the most demanding AI workloads. Experience the intersection of precision and power.

Multi-Pane Intelligence

Our revolutionary interface allows agents to manage multiple contexts simultaneously, mirroring a professional IDE workflow.

Global Context

Real-time awareness of your entire codebase.

MCP Integration

Native Model Context Protocol support.

Live Telemetry

Track token usage and latency in real-time with precision dashboards.

Autonomous Execution

Agents that don't just suggest, but execute.

Shell Integration

Direct terminal access for seamless deployments.

Developer Documentation

Developer Trust

Production-grade API with millisecond precision. Built for engineers who demand transparency, predictability, and raw power.
