How fast do you like to have it?
time mongosh "mongodb://user:password@localhost/?authSource=admin" --quiet --eval "db.getMongo()"
mongodb://<credentials>@localhost/?authSource=admin&directConnection=true&serverSelectionTimeoutMS=2000&appName=mongosh+1.6.0real 0m1.288s
user 0m1.457s
sys 0m0.118s1.5 seconds sounds not bad to me.
Actual connection time is even shorter (around 150 milliseconds) as you can see in the logs:
