expensive cpu usage on start and hungry in memory

[jozhuare99]

Type: Performance Issue

unlike other editor this one has a lot of features but the downside is very expensive usage of cpu on starting the app and when i save the changes on file the cpu is getting hungry again another one is the memory usage of this is very expensive, i think you need to build it from scratch again. you better build a new one using rust,

You can use the Start Extension Bisect command to investigate whether any of your extensions is particularly resource-hungry.

i disabled all of the extension and i will test it again.

all the extension are disabled this is when i snapshot of starting the vscode

this one is the snapshot when i typing and and changing some code

the memory usage are drop but it has a lot of cpu process all extension are disabled

then i tried to disable the internet connection

still no improvement on cpu process every letter that i type it compute very hard on cpu

why other editor like sublime and atom has nothing like this?

[amazingrv]

Not sure but it has something to do with filewatch changes in tsserver 4.9+ Please add this to you settings json object and restart to see if that works

"typescript.tsserver.watchOptions": {
    "watchDirectory": "dynamicPriorityPolling",
    "watchFile": "dynamicPriorityPolling"
  }

[jozhuare99]

not work ive uninstalled all extension and does some disabling some auto update and features and ive done to put that setting json code you provided but it still has no improvement maybe because its built in electron ? or its just the vs code way record every codes that coder inputted in the file. im either choose between sublime, atom and notepad++

Please share your workspace settings.json here

I actually use the vscode refined version but still had no changes on cpu are still oveloading on start and hungry on every type i made or changes it seems thats the way it is and i cannot do anything about it so this issue is closed.
