+#!/bin/bash
+
+# Purpose:
+#   This script sends HTTP requests with different content lengths to the 
+#   Semantic Router (Envoy proxy) and measures the response times. It's designed
+#   to help analyze how query length affects inference performance and latency.
+#
+# Usage:
+#   The script sends serial curl requests with incrementally increasing content
+#   lengths (configurable start, end, and step size) and records:
+#   - Request character count
+#   - Response time (client send to response received)
+#   - HTTP status codes
+#   - Full response content
+#
+# Integration with Metrics:
+#   This script can be used alongside metrics collection systems to correlate
+#   client-side response times with server-side inference metrics, helping to
+#   understand the relationship between query length and processing time.
