This repository provides a benchmark comparison between different versions of Perspective, specifically 2.10.1 and the latest release. The goal is to evaluate creation times and memory consumption to identify potential performance regressions.
The benchmark measures the following metrics:
- Total Duration – Total time taken for all operations.
- Worker Create – Time taken to initialize Perspective workers.
- Table Create – Time taken to create tables within workers.
- Table Update – Time taken to populate tables with data.
- View Create – Time taken to create views from tables.
- View ToJson – Time taken to convert views to JSON.
- jsHeapSizeLimit – Maximum JavaScript heap memory allowed by the engine.
- totalJSHeapSize – Total heap memory allocated.
- usedJSHeapSize – Heap memory currently in use.
How the Benchmark Works 1. A predefined dataset (data.csv) is loaded. 2. A Perspective worker is created. 3. 100 tables are instantiated for each worker. 4. Data is updated into each table. 5. A view is created for each table. 6. The view is converted to JSON. 7. Performance metrics are measured at each step. 8. Memory usage is tracked using the performance.memory API.
The latest version of Perspective exhibits higher memory usage and longer creation times compared to version 2.10.1.

This benchmark highlights a potential performance regression in newer versions of Perspective. Further investigation is needed to determine whether optimizations can be applied to improve memory efficiency and execution times.
