 # Benchmark and Profiling
 
 ## Benchmark
-- Benchmark a single static batch by running the following command without launching a server. The arguments are the same as for `launch_server.py`. Note that this is not a dynamic batching server, so it may run out of memory for a batch size that a real server can handle. A real server truncates the prefill into several batches, while this unit test does not. For accurate large batch testing, consider using `sglang.bench_serving`.

 To make sure the new model is well maintained in the future, it is better to add it to the test suite.
