Performance/Load Testing

[catch-21]

Description

We require performance and load testing on the Cardano Rosetta implementation. It would be good to take measurements using user scenarios. Once we define some acceptable benchmarks we are then able to detect any unacceptable differences in future.

Proposed Solution

Use a framework like https://github.com/alexfernandez/loadtest, or a tool like https://github.com/artilleryio/artillery.

Important Changes Introduced

Created some examples using Loadtest and Artillery. My preference is with Artillery. Non-preferred examples can be stripped out before merge.

Testing
