Originally created by @cdmihai on GitHub (Nov 4, 2019).

Originally assigned to: @DHowett-MSFT on GitHub.

Environment

Windows build number: 10.0.18362.0
Windows Terminal version (if applicable): 0.6.2951.0

Any other software?
Powershell 6.2.3

I get slow startup times (~6-7 perceived seconds). It started happening with Terminal 0.5.2762.0. It's particularly annoying when I start splitting off panes left and right.
I ruled out my $Profile script by printing out its execution time as its last command.

Let me know how I can give you any profiled data.
