I just found a case where Microsoft Visual Studio Code Terminal is capped to about 12,000 bauds. All you need is to print a log with lots of color escape sequences. I used tmux to compare the speed with the native terminal mintty. I can confirm it's only VS code's problem.

Why the SCM label ? How can you conclude that it's some Git SCM background process that's ruining the terminal performance ?

@Tyriar, could you please take a look at this? Thanks!

@meganrogge is this the problem you were seeing? I can't reproduce any issue here on Windows and I don't have my mac. If so could you try could get a profile to see if it's an issue on the renderer/window side?
