iBazel Benchmark Runner
This script runs iBazel on a specified target with the iBazel profiler enabled. After the initial build completes, it modifies a specified file by adding a newline to the end of it. The script reports the initial build time and the incremental build RTT.
It can also optionally launch chrome to a specified URL and report on the browser load RTT if the target (such as ts_devserver
) serves a website.
Reporting
The scripts outputs the RTT in ms as follows:
[ibazel-benchmark-runner] Initial build time 24059ms
[ibazel-benchmark-runner] Incremental build RTT 4192ms
[ibazel-benchmark-runner] Browser load RTT 4402ms
Usage
node_modules/.bin/ibazel-benchmark-runner <run_target> <file_to_modify> [--url=<url>] [--initial_timeout=<seconds>] [--incremental_timeout=<seconds>]
| Argument | Description |

| file_to_modify
| The file to modify in order to start in incremental build (a newline will be added to the end of this file). |
| url
| Url for the benchmark to navigate to in order to measure browser interactive RTT for incremental build (optional). |
| initial_timeout
| Maximum time to wait for the initial build (defaults to 300 seconds). |
| incremental_timeout
| Maximum time to wait for the incremental build (defaults to 60 seconds). |
| browser_timeout
