EngineTestObserver runs on the adblock task runner so it's unsafe to get callbacks on the main thread for the test runner
Brave Performance Predictor
This component is based on our blog post.
The current implementation is only for bandwidth prediction and uses a subset of the features discussed in the post for better cross-platform support. Key groups of features used are:
- URLs of blocked requests, from which we extract counts and distinct third-parties (e.g. tracking networks)
- total counts and sizes of loaded requests by type (scripts, images, fonts, stylesheets, media, document and “other”)
- basic page performance metrics (page load time, page interactive time, dom content loaded, first visual change, first meaningful paint)
The component includes:
- Generated linear regression model to parameters in a C++ header file (bandwidth_linreg_parameters.h)
- An interface to the model that buffers submitted features and runs the model when requested
