IndexedDB performance benchmark
A suite of benchmarks that can be run in your browser to assess IndexedDB performance.
- Measures with high-resolution performance.now()
- Tests set, get, getAll, bulkGet, indexed get, and readwrite mode
- Tests large numbers of object stores vs large numbers of records
- Adjustable test params (total, limit, iterations)
- Easily toggle individual tests
- Modular db interface for adding and comparing other storage mediums (e.g. in-memory, localstorage, etc)
Install
npm install
Usage
Run the development server:
npm start
Conclusions
- indexes are fast
- bulkGet scales well
- Chrome:
{ durability: 'relaxed' }significantly improves write performance - Safari: Large number of object stores results in massive slowdown of all methods
- e.g. 1500 object stores causes a single get to take ~100ms
- Use indexes instead of object stores
