Made an image compressor where you set how good the result must look, not a quality setting.

It finds the smallest file that still looks that close to the original, and shows you where the image changed.

Free, no sign-up. PNG, JPG, WebP, AVIF, GIF, HEIC.

@GTCrais @freekmurze Fair! I've run it for ~3 weeks on 4 production sites (~50K jobs a day) with no problems so far. If a safety check fails it falls back to stock workers on its own, and QUEUE_PREFORK=false turns it off completely.

[Ando Hakobyan @tevkert]

@tomschlick @freekmurze @laravel I sent it to a couple of people at Laravel after the release, but being new to X, I don't think it ever reached them 😅 If you try it on your workers, I'd love to hear the numbers.

[Ando Hakobyan @tevkert]

@myzoapp @freekmurze Its saves up to 80% RAM if you are running more than one worker on queue:work or any number of workers on Laravel Horizon (and uses half as much CPU and starts workers 6x faster).
And you don't have to change anything in your code.

🔗 Your Laravel queue workers keep 8 copies of your app in memory

@apnahive Nice for the per-worker cap. What it can't fix is that every worker carries its own copy of the compiled app. queue-prefork shares that copy across workers: 8 workers 645 → 192 MB, no code changes.

[Ando Hakobyan @tevkert]

@theo so you're saying there's room for improvement

[Ando Hakobyan @tevkert]

Is it just me, or does everyone burn the weekly limit in 6 days and then survive the last day at 99–100%? 😅

queue-prefork: cut Laravel queue worker memory by up to 80%

@taylorotwell hope my boy Omega is alright 🙏

[Ando Hakobyan @tevkert]

A Laravel Horizon worker takes ~56 MB.
A Laravel Cloud Flex box has 2 GB.
So it fits about 30 workers, right?

Wrong. It fits 210 with queue-prefork.

The same 210 on stock Horizon needed a Pro 16 GB box: $128/mo instead of $24.

Running Laravel queues with queue:work or Horizon?

Every worker boots your whole app and keeps its own copy of the compiled code in memory. 8 workers, 8 copies.

I made them share one: −70% memory for queue:work, −81% for Horizon. Drop-in, no code changes.

@PovilasKorop Forgot to cancel auto renewal of PhpStorm licence in august😅.
Worst purchase of the year, havent opened it since July.

[Ando Hakobyan @tevkert]

@adambalee If you ever decide to bring the checks back into Laravel: queue-prefork should take those 50–60 Horizon workers from ~4 GB to about 1 GB, with no code changes.

Something I measured lately: a Laravel Horizon supervisor takes ~56 MB of RAM, almost as much as a worker (~63 MB), and it never runs a single job.

6 supervisors ≈ 340 MB just to keep your queues organised.

I've been working on that. More soon.

[Ando Hakobyan @tevkert]

@BoringO11y No, I kept it all PHP and Horizon's own code. Supervisors and workers now start as forks of one small template that shares the compiled code, so a supervisor ends up around 6 MB.

Sharing the details later today 🙂

If you try it, reply with your before and after from queue-prefork:status. I'd love numbers from big fleets.

It's been running in production on my own apps this week.

One Horizon setup went from 1.16 GB to 282 MB.
