On 60fps every frame is displayed for about 16ms. So lags can only appear in multiples of 16ms. How do you come up with 1-2 ms delay per keystroke? To answer your question though: I find Slack's typing responsiveness acceptable. EDIT: To narrow down the source of your problem you might try to use Slack in the app if you are using it in the browser or vice versa.
