High Memory Usage

Describe the bug

Warp uses a significant amount of memory for a terminal. After using it for a day with 3-5 tabs open (sometimes closing and sometimes opening new ones):

After I close all tabs memory drops in half but is still 200MB

To Reproduce

Use Warp with multiple tabs.

Expected behaviour

Better memory management. When closing all tabs, memory should reduce to the lower (but still surprisingly high) 100MB which is what happens on start.

Thanks for letting us know, by any chance are you using any unsupported plugins in your rc files?

https://docs.warp.dev/help/known-issues#configuring-and-debugging-your-rc-files

[sullo]

I have oh-my-zsh enabled but I have just disabled it and will see how it goes.

[wzxu]

Just to chime in. Using the latest v0.2023.02.21.08.03.stable_01, I get 300MB memory usage freshly launched doing nothing. Kinda insane it uses more RAM than say Hyper, a terminal app build in Electron, which is supposedly as bad as it goes.

[davidtinker]

I have been running Warp on my Mac for a few weeks now with 20-30 tabs and it is now using 7G. I really don't want to have to close it to free that up. Maybe add an option to clear all blocks for all tabs or something?

[vorporeal]

Thanks for the feedback! Warp's memory consumption is something I'm working on; there should be some improvements to memory usage in the release coming out this Thursday, but there's certainly a lot more work we can do to improve things.

@davidtinker It's not as convenient as a "clear all blocks for all tabs" option, but you can hit "cmd+k" in a tab and clear all of the blocks in that tab. If you do that in all of your tabs and it doesn't drastically reduce memory usage, please let me know because that would be very concerning.

[davidtinker]

Cmd+k on all tabs cut memory from 7.2G to 2G. Thanks!

[jomifepe]

+1 on this, my swap is getting obliterated. This is what happens to me almost every time I unlock my mac and left warp open.

[vorporeal]

Holy moly that's bad. @jomifepe How long was Warp open for, in total, since you launched it? If you haven't restarted it yet, mind grabbing a process sample (from "Sample Process" in the ... menu in the Activity Monitor toolbar) and sharing it with me?

It has been open for about two days, but I often shut down the mac at the end of the day.

This is something that happens for about 15 seconds after waking the mac from sleep, warp freezes, as it spikes very high in memory usage and it then comes down to the normal.

Here's a Sample Process when it was "normal" (about 1.5GB). I'm not able to get it to spike really high right now, but I'm gonna try to get it once it happens.

[vorporeal]

Gotcha. Well, today's release (now live via autoupdate) makes some changes relating to memory usage which might fix this for you; give it a shot and let me know if it's any better.

[jomifepe]

Here are some more Sample Processes from memory spikes that I got:

• 16.89 GB
• 29.6 GB

[vorporeal]

Yep, that's about where I expected the issue to be. (We're spending a lot of time handling changes to the window size, which appears to happen on unlock.) I'll be starting on memory usage and resizing performance in earnest next week; might take a little while to make the necessary changes (rewriting some core data structures), but should improve things substantially.

That's great to hear, looking forward to those changes 🚀

[thoughtlessmind]

I am facing the same issue. I've 5 open tabs and it is taking 2GB.

---

although clearing the terminal logs using cmd + K drastically brought down the memory usage to 842mb.

[muescha]

to have more insight which tabs use many memory it would be nice to have a tab manager ( Tab Manager #2881)

[lrondanini]

same here, cmd+k cut the mem from 3G to 200M

[sandeepcmsm]

+1. even with 3 to 4 tabs goign for 2GB RAM, I have switched back to iterm for time being until this gets fixed.

[brockelmore]

any update here? 😅 cmd+k may work but ideally i wouldn't have to worry about this. This is 2 windows, total of 5 tabs

[vorporeal]

@brockelmore Whoa! How long had it been since you last restarted Warp?

[brockelmore]

@brockelmore Whoa! How long had it been since you last restarted Warp?

A few days - notably after running CLI app that produces a lot of text output many times fwiw

[etodanik]

Reporting similar issues with 700mb+ RAM usage. I was wondering why my laptop was freezing and turns out Warp was gobbling memory

[bcmcq]

+1 - Just spent some time hunting down what was slowing my machine and it lead me here.

2GB of memory for 1 window / 2 tabs monitoring local logs during development.

[zachbai]

Hey all, thanks for the reports. David (@vorporeal) had to divert his attention to a couple other issues but your feedback is heard -- we're actively investigating ways to address this issue.

[svenlombaert]

I have 6 tabs open with about 2 panes each, I just cleared them all with CMD+K but still getting high memory usage

[phase]

pls my ram can't take it anymore 😭

It seems to scale with how much text is present in the terminal. Closing & reopening tabs will free a good amount, but it quickly climbs up after continued use.

[bitttttten]

It's not as drastic, although Warp is usually the biggest contender for memory on my laptop too:

If I close all my tabs, about 6 open, it goes down to 150MB.

From discord user #rustyballz

Hello, I wonder if others have been having issues with Warp's performance... Pretty much weekly I am getting the following scenario you see in the screenshot. When I try to move the warp window or resize it even the smallest amount it will freeze for long periods of time, sometimes when it freezes it will shrink to this size shown and hide off screen, the only way to bring it back is to show all windows and drag it to a position I can see it. Also shown in this screenshot is the incredibly high RAM usage! My development flow has not changed since switching from iTerm2 and I never had these issues in that app even though I also had unlimited scrollback turned on.

[RoyzLevy]

Also here after using Warp for a few months now and liking all of the great features, but still getting big consumption of RAM on my system. Right at the moment I'm getting 2GB of memory for two open tabs which is making it really a hard time keeping using the tool and I'm ending up closing it every now and then during my work day.

[ericgross]

I am also finding it difficult to use Warp because it can't seem to handle a lot of content in the shell, which happens over time.

[chav-aniket]

+1 on this issue, been experiencing some terrible memory drain with warp. CMD+K helped the situation but would be nice for a more efficient app out of the box, love it a little too much to replace it :(

[hardskulls]

Same here. I'm usually looking at 700 MB - 1.7 GB of memory footprint.

[DmitryTokyo]

+1 on this issue. 3 days, 2 tabs, 4 windows. Usage memory is around 3GB. Switched back to iterm2 while this issue will fix

[jvsteiner]

This is an issue for me as well. I usually have about 3-4 tabs open, not too heavy usage, and typically memory consumption ranges from 700MB to 2 Gb. When it's higher, the responsiveness gets laggy as well, as compared to iTerm

[Dentrax]

Same here, Warp uses 7gb+ memory with 7 tabs on my Mac:

[dannyneira]

@garydgregory commented on #2964

When I start warp, it sucks up 833 MB GB of RAM! When I start iTerm 2 it sips 157 MB. Please fix... surely there's a better way.

[muescha]

You have warp with existing tabs? The tab history is sometimes long and consume a lot of ram

[Dentrax]

Is there any way to purge the history of current session? (And also set max limit in the settings)

Edit: I'm not sure if Clear Blocks is actual purge. It didn't change memory usage.

You can clear the tab with CMD+K, which clears all the blocks. AFAIK there's no option to set scrollback limits.

[ernest-ceevo]

Any update on this ? It is sucking 13GB of ram ... see the attached sample text Sample of CloudflareWARP.txt

[rreynier]

Today my system fully crashed after Warp basically stole all my memory 🤣 I took a screenshot with my phone since the computer was completely unresponsive and required a hard reboot. I had maybe 4 tabs open and 2-3 windows in each?

[jvsteiner]

this situation is a joke. I have uninstalled and went back to using iTerm2. When the electron app uses 10-50x less memory than the rust app, you know there is a design flaw.

Coming up on a year since I opened the issue.

[daUnknownCoder]

i am using the linux version it consumes 8% of my memory, disable some parts of warp toggle? like disable workflows or drive with keybind? ik i m using the AppImage executable so it has to be high but kitty used to be faster, i dont want to switch back to kitty but ig ligatures, 1 line prompt is all tellin my brain to switch but i dont want to pls solve this...

[franko-franicevich]

Same here, over 10GB on Mac cmd-K DID drop it right down, but I like my command history. iterm2 keeps it forever until I close the tab, or clear it intentionally, even between reboots, and does so with low memory footprint. Seems to me you shouldn't need to keep it all in ram.

[nevdelap]

On Linux, after about six hours. 😱 Vanilla bash, just a few aliases and env vars in my .bashrc.

I had a terminal tailing a log running for hours, might be related to that. Update: Seems not. I had several terminals open, and 10G virtual memory being used by Warp, and it stayed around while I Ctrl+Shift+K'd in one that was tailing a log, and stayed around until I closed the last one, which was new and had done almost nothing.

[nevdelap]

warp on Linux uses 170MB without doing anything at all, while having 5GB of virtual memory mapped. This example is htop running in xterm, I open a single warp terminal, and don't do anything in it.

Of course warp isn't expected to use as little as xterm, but this is the opposite, htop in warp and xterm opened without doing anything.

[mikelgmh]

Linux user here. ExtratermQT (Electron based terminal) is using 232mb with 5 terminals open. On the other hand, Warp is using 458mb with 4 terminals open.

Warp is using almost the double of RAM with 1 less terminal instance!

Update: As time goes by, seems like Warp is consuming more and more ram with no reason at all. No jobs running at any of the terminal instances.

[utterstep]

Same here, 2.4Gb used with 10 tabs

[jvsteiner]

This thread is so funny. I long ago uninstalled warp, but stayed subscribed for some/no reason. This is obviously a leak of some kind. I can't imagine that it would be too hard to find with a debugger. Worst case there are several leaks. It's not like it's hard to reproduce. What kind of developer writes code that leaks like this, and then leaves it in for over a year - in a developer tool! It would be funny, that is, if it weren't so sad.

I don't see anything funny here. The funny thing is that to still be able to see those who do not have the "blameless culture".

Every developer can make mistakes and the important thing is to learn from mistakes and then write some regression tests to prevent them from happening again.

You can contribute to project if your codes are "unleakable". I'd be happy to see having this issue resolved.
