SourceTree 2.6.3 (2.6.x) for Mac is horribly slow

[Nes-si]

Hi there.

With new design the app acquires a totally slow working. It regularly freezes and loads CPU a lot.

I've downgrade to 2.5.3 version and I got added evidence that the 2.6 is a problem. The 2.5.3 version works normally.

I've been using Sourcetree for years and in the last week or so it has gone horrendously slow for Mercurial Repos. Using a Macbook with Mojave. I also got a version error or something like that so had to reconnect my accounts.

Git repos opened in the same Sourcetree window are flying along, it's just the Mercurial repos causing issues as above, slow to do everything, load changes, commit files, push files etc.

I hope they fix it soon as it's painful using it at the moment.

It's really horribly slow.

Whatever you do, it just occupies almost all of the cpu, and takes really long time to respond.

Switched to Git, all is great now.

SmartGIT has come a ways recently.  I'm on a beta preview for release soon (obtained when I complained about something they have fixed in that release).

Now that it draws the branch tree as well as (even with better features than) SourceTree there's no reason not to swap if your organisation will pay or you're a non-commercial user.

I can really recommend this - I've done it and am still happily using 2.5.3, six months later.

[QuentinNev]

Gonna do the same, eight month later, 2.7.whatever, same perf issues. Hopefully i'm used to git commands so I can do without it. But for some tasks (i.e. resolving conflicts) it can be very useful, and for those not used to type commands.

Same problem on Mac OS X 10.13.4 with SourceTree 2.7.6: cripplingy slow, even on new & empty hg repositories.

Right click on toolbar, choose 'Customize Toolbar...' and drag refresh button to it.

[Martin Gregory]

How do you "add a refresh button to the taskbar"?

SourceTree 2.7.3 (4.0GHz i7 27" Retina iMac, 32GB)

I think it might be related to Retina displays? On my old 13" MacBook Air Sourcetree works fine, but on my i7 4.0GHz Retina 5K iMac it is utterly slow. Even typing of commit message has a ~1 sec lag before letters appear on the screen.

All other operations are also slow as hell. Every single change of view takes at least few seconds.

I agree that it gets worse when SourceTree is running for a long time. I restart it every day.

Probably also the number of opened repositories (windows) is important for performance.

One trick that improved CPU usage: I have disabled automatic refresh of local repository (it was triggered every time after new classes were compiled). Now I have to refresh manually but it is faster. For convenience, I have added the refresh button to the taskbar.

Thanks for the great idea about downgrading; it never occurred to me to try.  Downgrading improved performance, though I wouldn't quite call it snappy yet. Another benefit for me is that it fixed push, which broke a while back and I'd just been doing from the command line ever since.

Even though I've only worked in Mercurial for the past few days, SourceTree seems to have spawned a zillion git, git-credential-sourcetree, and git-remote-https processes that don't go away after quitting.  I wonder if clearing out my git repository bookmarks would help with all that.

[Benjamin Mullikin]

Yeah I am convinced /s this is Atlassian's passive aggressive way of encouraging us to use git through the command line. 

[torrelasley]

FYI, downgrading to 2.5.3 did not work for me. I had to go all the way back to 2.1 for the slowness to go away. It's lightning fast again, been struggling with this for 2 years.

[tomdearden]

I can second this - 2.6.x and 2.7.x both uselessly slow for even very small changesets on my 2015 Retina Macbook Pro.  I'd tried using System Git, turning off diff altogether and was eventually just using Sourcetree to see an overview of changes then using the command line to run diffs, build commits etc.

Downgrading to 2.5.3 has worked great and I'm now actually able to use Sourcetree as I used to - wish I'd thought of this myself!

[travisdetert]

I tried your recommendation as well, and it is like using a completely different application.  Night and day difference.  2.7 is VERY broken, and basically unusable on my 2009 macbook with El Capitan.  These are the most basic of operations as well, with not many pending changes.  Additionally it lags on submodule updates HORRIBLY.

I hadn't noticed until I was replying to your post, but I'm also on 10.11.6

[Christopher Mischler]

Same – Sourcetree 2.7 is hammering my CPU. I only have a couple files open, and they're all <5KB. It brings my entire computer to a crawl sometimes, for a minute or two (which is forever in developer time).

Mac OS 10.11.6, Core i7 2.3GHz 8GB

Downgrading to 2.5.3 seems to have fixed it. Wtf...

[Ryan Daniels]

Less than half the time when I switch to the system Mercurial instead of the embedded one.

[Ryan Daniels]

Version 2.7 (152)

High Sierra 10.13.2

Mercurial

VERY slow for me. Clicking on various revisions is very slow. 5-7 seconds with only 1-2 files changed.

[Steve Hoffman]

I rolled back to 2.5.3 from the Download Archives and turned off check for updates until there is an indication this has been addressed.  Good luck all!

[Bradley Gaynor]

Same its been unusable for months 

2.6.x sourcetree 

10.11.6  macOS 

[Natalia]

Same with SourceTree 2.7 and El Capitan 10.11.6!

Even navigating through file changes is painfully slow!

[Deleted user]

Same here, same versions

[Michael Wegner]

Some here ... High Sierra 10.13.1 ... SourceTree 2.6.3

Unusable. GIT checkout takes forever.

[aknabi]

It's gotten worse and really killed the workflow... our shop is looking for alternatives since Atlassian folks seemed to be still celebrating and maybe a bit tipsy from all the IPO champagne... sad as I've loved the products, but we're not forced by IT to use whatever is rammed down... it's time to find a toolchain that works built by folks that I guess are hungry.

[Josh Sacks]

Also having this issue on OSX 10.13.1 2017 macbook pro for Sourcetree v2.6.3. It crashed while I was trying to checkout a branch, and I've noticed that even resizing the window running the app is very slow. 

Downgrading to 2.5.3 also seems to work better for me.
