+API Benchmark
+-------------
+
+The following table shows latency benchmarks for the /recommend API endpoint. Tests were run with different combinations of query parameters and reranking options. Each request was made sequentially to measure individual request latency accurately.
+The summary statistics are generating from 50 runs with a timeout of 30 seconds w/ no delay between each request.
