See screenshot below. This is will all extensions off. I quit vscode at 2:49 and opened it again at 2:55. This time it only took 2 minutes to start eating CPU.

Please help, this is killing my battery life.

@ktravelet Can you please try collecting the typings installer log so that we can investigate:

1. Set "typescript.tsserver.log": "verbose" in your user settings and restart vscode
2. Reproduce the problem
3. In VS Code, open a js file and run the Open ts server log command.
4. This should open a directory. Please share theti-xxx.log file in the opened directory. This file contains the typings installation log

Thanks

Wow, the log grew to 50mb in a few minutes. Do you have a secure place to upload this? There's some sensitive info in there.

Run code --upload-logs on the command line and follow instructions (code-insiders --upload-logs if using an insiders build) to upload the log and share the log id.

I am thinking this is to do with using polling watch on all the files and directories that typing installer decides to watch.
