Performance improvements in V8

v1.0.5

Updates

• Improved performance

Notes

Benchmark tests have been changed so that every library uses the exact same test.

promise-queue and p-limit don't provide a promise that resolves when the queue is empty, so I was using Promise.all with an array of jobs. Which is how you use them in real life. But it's a slight performance hit and I don't want the tests to be different.

The updated results are in the readme.

v1.0.3

No new features or fixes. Just refactoring and adding new benchmarks like this one:

Cloudflare Workers benchmark

Library	Requests/sec	Total (sec)	Average	Slowest
@henrygd/queue	622.7809	1.6057	0.0786	0.1155

Full Changelog: v1.0.2...v1.0.3

v1.0.2

• queue.done can now be invoked in different contexts simultaneously
• General refactoring. Library is now at 332 bytes :)
• Added fastq and async.queue to the benchmark

Full Changelog: v1.0.1...v1.0.2

v1.0.1

Updates

• Add support for AsyncLocalStorage
• Refactor queue.done() implementation. Bundle now down to 342 bytes. :)
• Update benchmarks

Full Changelog: v1.0.0...v1.0.1

v1.0.0

Updates

• add done method which returns a promise that resolves when the queue is empty
• add clear method to empty the queue
• add size method to get the total number of promises in the queue
• add active method to get the number of promises currently running

Benchmark

Average of five runs passing Promise.resolve() through the same queue one million times on a Ryzen 7 6800H laptop using Bun 1.1.12.

p-limit is used for comparison because it's the most popular comparable library, with 117 million weekly downloads (!) as of June 2024. I've used it before and it's great.

Also included is the minified bundle size (no gzip) for reference.

Library	Version	Time (ms)	Heap size (MB)	Bundle size (B)
@henrygd/queue	1.0.0	512	37.4	352
p-limit	5.0.0	2,276	223.3	1,763

v0.0.1

Tiny async queue with concurrency control. Like p-limit, queue, or promise-queue, but a lot smaller.
