Canonical: https://bunqueue.dev/blog/bunqueue-v2-8-41/ --- Ships 3 performance improvements. pullBatch now parks delayed and active-group-blocked candidates in one scratch area for the entire batch, then restores them once before releasing the shard lock. ![](https://github.com/egeominotti.png?size=64) [egeominotti](https://github.com/egeominotti) #### To install bunqueue v2.8.41 ```bash title="bun" bun add bunqueue@2.8.41 ``` ```bash title="npm" npm install bunqueue@2.8.41 ``` #### To upgrade bunqueue ```bash bun add bunqueue@latest ``` ## Performance - `pullBatch` now parks delayed and active-group-blocked candidates in one scratch area for the entire batch, then restores them once before releasing the shard lock. This removes the repeated extract/reinsert cycle for every delivered job while preserving priority, FIFO groups, limiter accounting, long-poll deadlines and queue indexes. - Native benchmarks with 50,000 ineligible jobs and a batch of 100 improved active-group backlogs from roughly 1.54 seconds to 18 milliseconds (about 85x) and delayed backlogs from roughly 1.45 seconds to 16 milliseconds (about 90x). - Regression coverage verifies single restoration, partial batches under concurrency limits, earliest delayed wake-up and exception-safe restoration. ## Thanks to 1 contributor! - [@egeominotti](https://github.com/egeominotti) --- [← bunqueue v2.8.40](https://bunqueue.dev/blog/bunqueue-v2-8-40/) · [Release on GitHub](https://github.com/egeominotti/bunqueue/releases/tag/v2.8.41) · [Commits since v2.8.40](https://github.com/egeominotti/bunqueue/compare/v2.8.40...v2.8.41) · [Full changelog](https://bunqueue.dev/changelog/) · [All posts](https://bunqueue.dev/blog/)
