Improve Scratch's memory management.

yavuz61035

even loading up a complicated roblox game is better than a medium-sized scratch game at this point

my device: My browser / operating system: IPad iOS 15.5, ChromeiOS 103.0.5060.63, No Flash version detected
i have 2gb of ram
loading up a moderately sized generic platformer would probably crash chrome

this is bad. scratch should fix the memory usage.

at this point it may be your devices causing the problem, not scratch
anyway support. a performance upgrade is something we all need. it's 2022 now. scratch is almost 2 times older than most of it's users for goodness sakes.

If an relatively new MacBook Air with 16GB of RAM is struggling, then it's probably Scratch

Not everyone has 128GB of RAM

Test how good your computer is at doing math. 3DS and Wii U online after shutdown.

scratch 3.0 came out in 2019, most scratch users are well above 6 years old

re-read the OP and im sure you'll understand that is not the case

I have 4 GB of RAM and 3.6 GB of free disk space. It took Chiroyce 14 GB of RAM for the project to load. I am honestly quite interested in what could happen (either something mundane will happen, like my computer restarting, or something crazy can happen) but I don't want to risk it.

I risked it with 8GB and this happened and it stopped responding after I left the tab

A 2-minute video converted to gif is I think more than 100 mb, so how does this even add up to 14 gb?
I also know there is a simple crash script that can fill up your ram almost instantly and freeze your computer, it's like 5 blocks or something

Please don't remove the automatic browser/OS info after making a new Bugs and Glitches forum post, that information really helps a lot!
(unless you are reporting from a different device, then you should specify what device, OS, and browser you have)

Support. And while we're at it, maybe reduce project file size on the server? Seems a little wasteful (and insecure) to have the project.json stored uncompressed on the server.

const juniper = programmer && musician;
// my pronouns are she/her
// i am trans and bi :P
// you can call me june or juni for short but i prefer juniper

python version:

juniper = programmer and musician
# my pronouns are she/her
# i am trans and bi :P
# you can call me june or juni for short but i prefer juniper

hmmm

Debug.Log(“Unity too!”)

<?php echo “PHP is weird!” ?>

Ok, why isn't the JSON compressed and encrypted? I might be able to exploit stuff like this!

Forkphorus doesn't have an editor. Imagine you're the creator of a project with 4000 assets and wants to make a change to it:

I'll go ask @GarboMuffin to improve memory usage for turbowarp.

Support. The reason why I can run these projects is that I use a system with minimal ram usage (Fedora Linux) with 16 gbs of RAM and 8 gbs of swap on a nvme. While running these projects, my computer just feels sluggish.

ask [why] and wait

HUGE support, honestly it's stupid how much memory a more complex project uses. I had to cancel one of my older projects (that had 2k costumes in it) just because so much memory was being used that the project was too laggy. My newer project is near 600 costumes now and is starting to lag from memory usage too. Knowing how long it takes ST to implement simple features, I highly doubt they'll actually implement this but I can only hope that they do

Nothing to see here

It looks like this topic hasn't been posted on in a few months, so I'd like to bump it so it gets more attention. Scratch's memory management urgently needs to be improved. I have 8 GB of ram and I can't work on big animations.

I'm not sure if that's possible, since the comparison between Scratch and Forkphorus/Turbowarp isn't fair. Scratch converts Scratch code into Javascript on the fly, whereas Turbowarp compiles first. I'm not an expert in these sorts of things but I think that reduces memory usage by a lot.

You guys are over thinking this, just clear your browser cache.

That doesn't work with projects that have thousands of assets

Thousands of assets, way more space than you have, etc:
This only works if you have enough RAM in the first place.
