Anecdotal, but with 5 workspaces joined, Slack idles between 0-2% while on the foreground for me.

This is a fairly modest i7 3770k based system. Their work on reigning in runaway CPU usage truly seems to have paid off.

Calling a 3770k modest is a stretch but I have a mobile dual core here (OK, it's a Kaby Lake but still) and also seeing 0% in Task Manager.

If having a six-year-old CPU isn't considered modest, it really says something about the lack of progress in the CPU space.

We discussed this recently: from Sandy Bridge to Kaby Lake , IPC grew 20%, power consumption dropped brutally. And by Kaby Lake progress has completely stalled due to Intel's inability to switch to 10nm allowing AMD to catch up.
