I just wanted to second Matthias247's comment: why is this a problem? I'm sitting in front of a 4 year old iMac. I have VSCode open currently with 3 windows containing 3 projects and code in 5 languages. The total CPU load for the aggregate 22 process group is less than 1% and while it's not using no memory it's not using more than, say, Chrome or Slack use.
