Sublime consumes cpu on Mac after update

#73

I’ve started up on my laptop, after waiting for everything to settle down, low CPU usage and no other windows visible. I’ll paste the start-up log below.

On the other hand, I’ve seen some laggyness when testing my game. I think refreshing the browser causes a build artifact, which causes an index operation, and since the build is still on-going, both processes get slowed down. I’m sure Dropbox, github and the windows file scanner all want their piece of the pie at the same time, when I really need my CPU to finish the build ASAP.

Unfortunately, the index log doesn’t reveal which file is being scanned, so I don’t know what to exclude. sublime.log_indexing(True) has no effect on the output of the indexer in the console.

I’m also adding a screenshot of ProcessExplorer during one of the freeze episodes. It jumps to 10-35% CPU usage and becomes unresponsive for several seconds. Sometimes, clicking on it causes the window to “white out”, which seems to be a windows 10 thing fro unresponsive processes.

Thanks for your help!

Sublime Text is also consuming large gobs of CPU for me as well. Just having Sublime Text in the background makes my computer get hot and my fans spin. I have macOS Mojave 10.14.4 on a MacBook Pro (13-inch, 2018, Four Thunderbolt 3 Ports). I have “Version 3.2, build 3200”. My indexing status is idle.

I have a git repository in my user folder. I use it to keep track of changes to my bash profile files, and nothing else. I know that this is probably not the best way to track these, but it hasn’t caused me any problems up until now.

You’ll want to disable git status in that case.

I’ve had the same problem with CPU after update on v3.2 Build 3200. I set <“show_git_status”: false> in settings and fixed it.

SublimeText 3 (Build 3207) is killing my CPU on OSX 10.14.4 as well. There is no ~/.git folder, however.

Since you are on 10.14.4, try setting gpu_window_buffer to false in your Preferences.

Sorry, but 3.2 is the worst version ever (unless git integration is disabled)

Will give that a go, thanks @wbond!

Had the same indexing issue. CPU struggling to index 200k+ files. Ignoring any dependency libs (node in my case) fixed it immediately.

"index_exclude_patterns": ["node_modules/"]

As far as I can tell, dfn/symbol lookups still work fine for my project files. If I’ve made a mistake by excluding node_modules, I’m open to other suggestions!

This worked for me. Thank you!

Indexing was stuck, and made my computer completely unusable. I really think this needs to be fixed.

On my Mac (Mojave 10.14.6), I had disabled the indexing and git status line, but still got an enormous number of scan: ... lines and CPU usage, even when none of the open files referenced a git repo.

I eventually shutdown ST3 (build 3207 BTW), ran rm "${HOME}/Library/Application Support/Sublime Text 3/Local/*.sublime_session".

On restarting the problem has gone away. I suspect that ST3 crashed at some point and left behind references to the .git repos that caused the problem.

I’ve been using Sublime for years and love it, but lately performance issues are making my MacBook completely unusable.

I’ve read through this topic and tried various suggestions…

I’ve tried setting show_git_status and gpu_window_buffer to false.
I’ve deleted the session.

I’m on 3.2.1 / 3207, on macOS 10.14.6 (18G84).

Every time I save any file, it rebuilds the entire project index from scratch - is that how it’s supposed to work?

I can wait for the indexing to finish (several minutes), but as soon as I save a file, it starts again. If I don’t wait for it to finish, it starts again. It’s always indexing! Given how much CPU that consumes, I can’t get anything else done.

At the moment, I have no alternative except to disable indexing, which is a shame as “goto” is really handy.

Any ideas?

Could you check the sublime indexing status: Help>Indexing Status…, as well as try reverting to a freshly installed state.

Just installed Sublime 3.2.2 for the first time ever. I’ve never used it before, but I like what I see, at least for the first minute or so. Now it’s spiking my CPU and is almost unusable. Tried https://www.sublimetext.com/docs/3/revert.html but no luck. Also, checked indexing status and its “idle”. I’m on macOS 10.15.4. :frowning:

Could you post your console output?

Trying to figure out what you’re referencing. I see that question being asked a lot in this thread, but as I am new to Sublime, I haven’t yet found the document on how to produce what you’re asking for.

The Sublime console is a panel that you can open at the bottom of the window that shows status messages from Sublime, your plugins, etc. You can get at it by using View > Show Console from the menu or using the key binding that’s displayed there (or via the panel chooser menu in the bottom left of the window).

Ah, of course. MacOS now lists Sublime as “using significant energy”, but at least the fan hasn’t started running this time. It was non-stop last time. Not sure what’s different this time. I’ll keep using it and if it happens again I’ll capture the console right away. For now, hopefully something below helps…

Thanks!

I have not up upgraded, using sublime 3 for many months, no new extensions/addons installed but all of a sudden there is a spike rendering it useless.

The indexing will parse all of the code in any folders you have open, which can take a while when you first open a folder, especially if the folder contains many thousands of files.

Future releases of Sublime Text will have some improvements to the performance of indexing, which should minimize this.

The other thing that can consume a lot of CPU is if you open a large folder with many filesystem events happening. For instance, if you open your user home folder, Sublime Text gets filesystem notifications about every file creation, modification and deletion. With a home folder, this can be quite a lot of activity.

If you are using Package Control a new version of a package may have been installed. The way to test would be to see if https://www.sublimetext.com/docs/3/revert.html helps.
