Issue Type: Performance Issue

Working with this version was no longer possible so I had to downgrade to 1.52, with works as usual. The Extension Bisect tool didn't find any critical extension.

To make any progress on this issue the dev team will need the performance reports from when 1.53 is installed and the problem is happening. The information you submitted here is from 1.52.1.

See also https://github.com/microsoft/vscode/wiki/Performance-Issues

gjsjohnmurray commented 3 years ago

Alternatively, install Insiders (1.54) alongside your downgraded Stable (1.52.1) and try to reproduce the issue there.

MiriPii commented 3 years ago

I have the same issue with the current stable and insider -builds on CentOS7, installed from official rpm-repo. Unfortunately, the Report Issue-tool is not functional for the affected builds.

Affected builds (that I tested) on my system:

No issues with previous stable rpm (1.52):

Behaviour

Watching at htop for a while, I could see that the process spun up each of the cores to the max one at a time.

Might relate to #115784

Tyriar commented 3 years ago

The process information isn't showing any process consuming much CPU, do you know what process is causing the problem?

gjsjohnmurray commented 3 years ago

@Tyriar the performance data posted by @jungand seems to have been generated after downgrading to 1.52.1. I have already requested new info.

As I said in my post as well, the Report Issue-tool is not functioning at all with the builds that consume a lot of CPU; namely rpm-builds v1.53.0 and 1.54.0-insider. My and OP's system statistics are from the working build (1.52).

We need another way to debug this than the Report Issue -tool, any suggestions?

gjsjohnmurray commented 3 years ago

@MiriPii the underlying problem is detailed in #115784. Versions after 1.52.1 are currently giving various problems on RHEL7/CentOS7 etc.

deepak1556 commented 3 years ago

I will document in the other issue about the issue with RHEL7/CentOS7, tl:dr; it is not supported officially from v1.53 and above.

jungand commented 3 years ago

sorry, had to finish some work on my project before I got some minutes to dive deeper into this issue.

The 'Report Issue' function doesn't open so I've created the output this way:

$ code --status (electron) Sending uncompressed crash reports is deprecated and will be removed in a future version of Electron. Set { compress: true } to opt-in to the new behavior.

I tried to 'Disable All Installed Extensions' but this didn't have any effect.

Then I've installed code-insiders-1.54.0-1612761896.el7.x86_64.rpm and started it up with no extensions installed. Still 100% CPU usage.

Thanks, this is dupe of https://github.com/microsoft/vscode/issues/115784 , RHEL 7 is not officially supported with 1.53 and above, you can check https://github.com/microsoft/vscode/issues/115784#issuecomment-775224787 for fixing the cpu usage.
