"""This script runs an automated Cronet native performance benchmark.
This script:
1. Starts HTTP and QUIC servers on the host machine.
2. Runs benchmark executable.
Prerequisites:
1. quic_server and cronet_native_perf_test have been built for the host machine,
e.g. via:
gn gen out/Release --args="is_debug=false"
autoninja -C out/Release quic_server cronet_native_perf_test
2. sudo apt-get install lighttpd
Invocation:
./run.py
Output:
Benchmark timings are output to /tmp/cronet_perf_test_results.txt
