Huge Slowdown #62421

Closed hipstersmoothie closed 5 years ago

hipstersmoothie commented 6 years ago

In the past two days VSCode has become unusable. Currently it y freezes every 5 minutes and has to reopen itself.

jkells commented 6 years ago

Having the same issue, every 5 minutes or so the window freezes, sometimes it recovers after 30 seconds or so. This is a medium sized typescript project running webpack-dev-server in watch mode as a build task.

Version: VS Code version: Code - Insiders 1.29.0-insider (97ad72a02c351d6cde0fd32b41d9700a43e5964a, 2018-10-31T06:11:22.318Z) OS version: Darwin x64 17.7.0

Edited to add process sample: sample.txt

I wasn't able to open dev tools inside VSCode.

Extensions I've got installed:

I am experiencing the same problem. Console.app shows the following errors, mot often associated with opening files. That is also when the 30-second plus freezes seem to be happening.

libnetwork.dylib 0 error 92506: 0x365b5c 00:19:16.743646 +0100 0x365b5c 92506 Code - Insiders Helper 0 nw_path_close_fd Failed to close guarded necp fd 35 [9: Bad file descriptor] Of note: the system does not react to input during these freezes, yet neither CPU, nor I/O rate or RAM seem be excessive. The "spinning beachball" type of event is associated with I/O issue IIRC.

Now it just disproved me with 200% CPU usage for a minute while being unresponsive. I managed to to take a sample of the process (see attached). I have approx zero experience this close to the OS, but the word "mutex" does seem to appear an awful lot?

I also found several of the following reports in the automatically generated diagnostics (Sorry for the long quotes instead of attachments–github does not like these files):

Experiencing the same problem

kieferrm commented 6 years ago

@hipstersmoothie @jkells @MatthiasWinkelmann @Astrantia does that also happen when launch --disable-extensions.

hipstersmoothie commented 6 years ago

I am on a typescript project as well

Chandu3245 commented 6 years ago

Its very much annoying, freezes for every 5 minutes.

chrmarti commented 6 years ago

Everyone: Please try running with extensions disabled (--disable-extensions) and acquire a performance profile (https://github.com/Microsoft/vscode/wiki/Performance-Issues) during the slowdown/freeze.

jrieken commented 6 years ago

Can anyone create a CPU profile of the renderer? The process is explained here: https://github.com/Microsoft/vscode/wiki/Performance-Issues#the-rendererwindow-process-consumes-a-lot-of-cpu

jkells commented 5 years ago

@jrieken I tried, left the dev tools open while I've been working so I could run it when it freezes. Unfortunately it just hangs Profiling... can't click stop. Haven't tried without extensions yet.

jkells commented 5 years ago

CPU-20181106T110946.cpuprofile.zip

CPU profile attached, extensions weren't disabled but it still might help you. It took about 60 seconds to open developer tools, I was able to do it from the help menu not the F1 menu. I hit stop on the profiler after about 5 seconds but it took about 5 minutes to actually stop.

jkells commented 5 years ago

This could be anecdotal but I feel like it's happening much more regularly when I have webpack-dev-server running as a build task. It didn't happen yesterday morning while I didn't have the dev server running.

jrieken commented 5 years ago

Thanks @jkells! This is really helpful. It seems like an insane amount of IPC messages are being received by the renderer. Those messages are most likely coming from file event, search, or debugging (telemetry). I don't think that the latter two cause this, but my suspect is file watching, esp since you have mentioned the webpack-dev-server.

screenshot 2018-11-06 at 09 12 04

@jkells Can you use the files.watcherExclude property and exclude suspicious webpack folders? Like temp folders which contain compilation artefacts and things like that

jrieken commented 5 years ago

@hipstersmoothie @jkells @MatthiasWinkelmann @Astrantia are you guys using webpack-dev-server too? Or some other build tool that creates/writes/deletes many, many files?

Astrantia commented 5 years ago

@jrieken I'm using Latex. The extension is provided by https://github.com/James-Yu/LaTeX-Workshop

I know it's watching over files and sometimes writing and deleting ones, but it's not on bar with webpack.

I'll try to get a hand on profiler too.

Anyone using a multi root workspace (foo.code-workspace-file) or is this just with having a folder opened?

Astrantia commented 5 years ago

@jrieken I'm on Windows and no multi root workspaces. I wanted to take a look in --verbose, but I can't trace the logs in verbose because of the following error message:

jrieken commented 5 years ago

@jkells Any chance that you can share that project with us?

hipstersmoothie commented 5 years ago

Not in a workspace, just a folder. Running my dev server in iterm and still getting the slowdown

jkells commented 5 years ago

Can't share the project sorry, I've been running without extensions for a few hours without any crashes

MatthiasWinkelmann commented 5 years ago

The problem disappeared for me at around the time I disabled extensions, and has not reappeared even after enabling extensions again. This may be due to working on different projects (with different setups for webpack-dev-server and similar), but I suspect some intermediate update may have fixed it.

jkells commented 5 years ago

No crashes for me yesterday, going to re-enable extensions and see what happens

hipstersmoothie commented 5 years ago

Still present for me. Had to force quit around half a dozen times today On Wed, Nov 7, 2018 at 3:32 PM Jared Kells notifications@github.com wrote:

@jkells seems like we are getting closer to this. did I get that right? this went away with disabling (some?) extensions? Unrelated to webpack-dev-server?

Thanks for creating this issue! We figured it's covering the same as another one we already have. Thus, we closed this one as a duplicate. You can search for existing issues here. See also our issue reporting guidelines.

Happy Coding!
