It's not always a good thing. It could be a good thing situationally. Such as on a machine with limited memory available to it.

Allocated memory, or RAM, is a symptom of data that you don't need to calculate or download again. So, if every program allocated as little memory as possible, your user experience would likely degrade quite a bit.

This is why some larger applications take a long time to start up, the first time they are started since the computer has been booted, or havent been started in a while.

Typically allocated memory is yielded to newer processes (or active processes) as needed, sometimes via dealocation, and sometimes via swap mechanisms, so really it all just comes down to performance.

Most of the time, unless you're really constrained with memory, you don't need to worry about it a whole lot.

And if you are really constrained, only really adding memory will improve that significantly.

I mean, you might be able to choke one program to allow two to run more comfortably simutaniously, but you can only really work with what you have.

I've never run roblox, but in some cases, say with minecraft, you absolutely would want it to allocate more. It would allow smoother handling of laege worlds, and of course with mods loaded.

A pretty good question, a lot of people really dont understand memory, and offer bad advice anyway.
