Zed uses lot of RAM
Check for existing issues

Describe the bug / provide steps to reproduce it
Here zed is using around 2GB of ram and I have checked it on Reddit some people were saying their device is showing just 200mb to 300mb of ram usage with these kinds of project.
Environment
OS - Fedora 40 Workstation Hardware Model - ASUSTeK COMPUTER INC. VivoBook Processor - AMD Ryzen™ 7 5800HS Memory - 16GB Gnome - 46 Linux Kernel - Linux 6.10.11-200.fc40.x86_64

Quite recently, Zed took up over 2GB of RAM in my case. Despite everything, it is still software in a very development stage - anyway, such situations should not occur when it advertises itself as a very light editor.
Yeah I agree, Will see if this gets fixed in the recent updates, I hope they are working on this.
Hey @tanaybhomia, we have a handful of other issues about high RAM usage; do any of these cover what you are experiencing here? I'd like to consolidate the issues, if so:

Why is Zed spawning so many instances of rust-analyzer?
I've also noticed something similar whenever Zed is using a lot of RAM, it always has multiple instances of every active LSP server running. It seems like Zed is starting up new instances of the LSPs without shutting down old ones for some reason?
Zed will occasionally freeze and consume upwards of 9GB of ram, no idea what the cause is.
not sure why, not too many files opened but zed started to consume up to several hundreds of gigabytes, and it's quite reproduceable
Why is Zed spawning so many instances of rust-analyzer?
Have you checked that if it is spawning Rust analyzers like https://github.com/zed-industries/zed/issues/18673#issuecomment-2430108163 comment says
This is something I wish to know, too. I believe it is related to how many crates a workspace has:
- I have 26
Cargo.tomlfiles (1 is the workspace root, 2 are not part of the workspace, 23 are listed as workspace members) - Zed has spawned 27 rust-analyzer processes
- The result is that Zed + child processes currently use 20 GB of memory.
In case it helps, here is my lsp configuration:
"lsp": {
"rust-analyzer": {
"initialization_options": {
"cargo": {
"features": "all"
},
"procMacro": {
"enable": true
},
"diagnostics": {
"disabled": ["non_snake_case"]
},
"checkOnSave": true
}
}
}
Potentially relevant: #20767
@edfloreshz how many rust-analyzer processes do you have and how many Cargo.toml files are in your folder?
@maan2003 Since you seem to have the same issue: Same question to you
I think it was fixed by https://github.com/zed-industries/zed/pull/21787
cc @ConradIrwin
I have a single Cargo.toml with 7 rust-analyzer processes open at the moment.
it is due to multi buffers, if you restore a multi buffer it will start rust analyzer every time
This issue is getting serious it seems. I open log files ranging from 50mb-200mb. And ZED consumes 19GB of memory for some reason on my 16gb MBP. Also if you keep it open it increases constantly.
And another major issue is when I click to close the file. Entire Zed becomes unresponsive in Mac with that colorful circle kept on spinning. And I have to kill Zed to close it.
I tried to do this in vscode and the ram usage wasn't too much. But This Ram issue is getting out of hand now. Every update I'm waiting for this issue to be listed in the changelog. 😞 .
Hope the team takes this as priority as well.

Since A picture is worth a thousand words, Here are some screenshots for proof. Only One instance of Zed is running and I've closed the log files that I've opened. Still it's consuming 5.5GB of memory for some reason.
I found a repro for this

What are you using that has so much RAM to give to processes?
Temporary switched to other editors hoping to see RAM issue fixed in future version changelogs
I saw that Zed is using an older version of cosmic-text on Linux (version = "0.11.2"). It should be updated to the latest version (0.13.2), which contains a lot of memory usage optimizations.
I also didn't see any malloc tunables being used, so I'd highly recommend setting a static M_MMAP_THRESHOLD on Linux to a reasonable value on application startup. libcosmic has malloc functions declared here which get called early on application startup like so.
If you don't set a static MMAP_THRESHOLD, then GNU libc malloc will dynamically increase its mmap threshold—the threshold where malloc chooses between using in-process brk arenas for smaller allocations, and OS-allocated mmaps for large allocations. This can result in a lot of memory fragmentation that will never be trimmed and freed back to the OS.
GNU libc malloc also does not automatically trim its brk arenas, so it can be necessary to malloc call malloc::trim(0) after an expensive operation has freed up a lot of memory. If desiring to use mimalloc on Linux, it also has similar trim functions.
As of today, zed seems to spawn rust-analyzer instances (in a loop maybe?) until it runs out of RAM (I have 64 GiB) and Ubuntu crashes.
This is for compiling a hello world Bevy project (I exit before it runs out of RAM in this case):

~~I am experiencing the same problem here. Zed's node server consumption increases to 2-3GB for a small project.~~
Environment
- Macbook Pro M3, 16GB
- OS version: Sequoia 15.3.1
EDIT: Was on mistake on my end. Python code analysis was configured to analyze all files within a workspace and not only opened files.
24GB of RAM when Zed was on background for an hour with a little C project opened.
Seems I find something related to use a lot of RAM (may be already mentioned by someone)
- [0 s] Start
htopto see memory usage before startzed, we see 3.5G RAM are used - [0-15 s] Start
zedand run python script for generate two json files. First one with indents, second one without. RAM usage up a bit on generation and return to normal value 3.8G in the end - [15-23 s] Open json file
indent.json(40 Mb), it opens instantly but RAM usage jumps to 5.0G - [23-50 s] Now lets switch between script and this json file - we will see that RAM usage are increased at every opening
indent.json. Now RAM usage 7G - [50+ s] Lets open json file with no indents
noindent.json(also 40Mb). Andzedfreeze for more than 2 minutes and takes 8G RAM (from 7G to 15G)
