Incremental Garbage Collection
| Feature | Status | Release Target | Dev Lead | QA Lead | Status |
| Incremental GC | Landed | Firefox 15 | Bill McCloskey | Ioana Budnar | In Progress |
Summary
- Garbage collection time is divided into short increments. Overall, the same amount of time is spent doing garbage colletion, but each individual pause is shorter.
References
Use Cases
- Use Firefox with incremental garbage collection enabled. When IGC is enabled, dynamic content on the web should have more tolerable pauses (possibly go from noticeable pauses to ones the user cannot notice).
- Disable incremental garbage collection.
Test Cases
- The test cases for this feature can be viewed here.
