Octane's goal is to measure the performance of JavaScript code 10found in large, real-world web applications. 11Octane 2.0 consists of 17 tests, four more than Octane v1. 12""" 13 14import os 15 16from metrics import power 17from telemetry import benchmark 18from telemetry.page import page_set 19from telemetry.page import page_test 20from telemetry.util import statistics 21from telemetry.value import scalar 22 23_GB = 1024 * 1024 * 1024 24 25DESCRIPTIONS = { 26 'CodeLoad': 27 'Measures how quickly a JavaScript engine can start executing code ' 28 'after loading a large JavaScript program, social widget being a common ' 29 'example.
