High CPU usage while coding in python #58030

Closed jjaimon closed 5 years ago

jjaimon commented 6 years ago

Issue Type: Performance Issue

Code is consuming alarmingly high CPU when ever I code in python. I've been noticing this for the past 3 weeks. It was okay before that. I'm suspecting some extensions or configuration, but unable to figure out which one. I'm also wondering if the breadcrumbs feature is causing it as I see continuously moving line next out "Outline" view on the left panel as I type.

When this problem occurs, in a command prompt try running code --status and share the output of this command. Alternatively, run ps aux | grep code to see which specific process has the high cpu usage

jrieken commented 6 years ago

Hm, the process info doesn't seem to reveal much... Can you try to include more or try the code --status command again? Also, an update to 1.27.1 might help.

jjaimon commented 5 years ago

I've been using 1.27.1. BTW, I disabled the plugins reported earlier and see a difference with respect to CPU usage. I'll keep this issue under observation now.

jrieken commented 5 years ago

k - likely that this is an issue with python extension

I'm also getting high CPU with the Microsoft Language Server for Python.

Following another vscode issue it was suggested to disable jedi which I've done. Also it was suggested that the linter could be the reason for the high cpu so I've tried pylint, pyflakes, and now on pep8. I have doubts about it being the linter.
