App Install

Measure app installation speed. This scenario has two roles:

minimal: Installs a simple app which implements initialisation callbacks but otherwise doesn't contain a lot of code.
large: Installs a larger app that contains some dependencies and some generated data as padding to make the bundle larger.

These are intended to catch a compilation slowdown or issues with copying around large WASMs (e.g. accidental cloning or tracing). In each case, the behaviour will uninstall the app it installed so that it can re-install it on the next iteration.

First Call

↑ Back to index

This scenario installs a simple app which implements the init callback, and measures the time elapsed between start of install and calling init. It will uninstall the app it installed so that it can re-install it on the next iteration. This is required to re-run the initialisation callback.

Validation Receipts

↑ Back to index

Creates an entry, wait for required validation receipts, then repeat. Records the amount of time it took to accumulate the required number of receipts for all DHT operations. This is measured to the nearest 20ms so that we don't keep the agent too busy checking for receipts.

Each agent in this scenario waits for a certain number of peers to be available or for up to two minutes, whichever happens first, before starting its behaviour.

By default, this scenario will wait for a complete set of validation receipts before committing the next record. If the NO_VALIDATION_COMPLETE environment variable is set, it will instead publish new records on every round, building up an ever-growing list of action hashes to check on.
