Are you using the ram for something else? Would you prefer to have 30 out of 32gb sitting unused?

Ram is cheap, I don't see why people complain that it's being utilized. Doesn't bother me at all.

I haven't looked into it but I would assume you can disable these unnecessary plugins if you don't want them?

It sounds like your perception of how a computer works is incredibly flawed. ram doesn't sit unused, the kernel uses it for caching and locality. The more RAM you give the kernel, the more you can have resident in the slab cache, the page cache, the filesystem cache, the network backlog, etc. Even on very large machines with more RAM than an average desktop, the kernel can still make use of almost all of it.

I work on efficiency so when people say things like "it's ok for my IDE to be an inefficient pile of garbage that locks up resources" it makes me wonder what kind of program they are producing.

You're both right. The issue here is that both the JVM and the kernel use algorithms that can use all your RAM to speed things up, and there's no good way to know which side should 'win' (to get the best performance).

Historically the JVM will happily use all your RAM even if it doesn't need to, because that reduces the amount of GC work required which increases CPU time available to the IDE for analysis and other tasks. It can be told there's a limits, in which case it'll spend more time GCing to stay under it.

Modern JVMs changed this old default and will wait until the app is idle then start reclaiming memory and releasing it back to the OS. I guess it depends what you mean by "mid sized" but 10GB is quite a bit. It'd be worth checking that everything is running on a recent JVM. Gradle in particular can be a hog if you run it on old JVMs.

I use Rider for .Net and WebStorm for JS. Before I left work I checked, with our small/medium sized project each of them were using a little under 2gb according to windows Task Manager. Adding in some other related processes I'd estimate the two combined might be using 5-6gb in total. So I have at least 26gb left over.

To quote Lord Farquaad: That is a sacrifice I am willing to make

I didn't say it's an inefficient pile of garbage. It's obviously making use of the memory in order to provide information and quick navigation etc.

My computer works completely fine while I have multiple jetbrains ides and browser windows, Docker etc running.

So maybe your perception is the one that's flawed. I know for a fact that my computer can handle it, but it seems like you mistakenly believe that it can't?
