MongoDB first request takes ~45s on Windows

Bug description

The first request takes a long time because prisma is trying to connect to the database for the first time, when I send the second request after the first request is finished, I get a response in a very short time. How can i fix this?

How to reproduce

Expected behavior

No response

Environment & setup

• OS: Windows 11
• Database: MongoDB

Prisma Version

3.8.1

I think that worked:

λ npx prisma@3.10.0-dev.57 db pull --url mongodb+srv://prisma:[e-mail]/test?retryWrites=true&w=majority
Prisma schema loaded from prisma\schema.prisma
Environment variables loaded from .env
Datasource "db"

Introspecting …

✔ Introspected 1 model and wrote it into prisma\schema.prisma in 123.33s

Run npx prisma generate to generate Prisma Client.

vs.

λ npx prisma@3.10.0-dev.58 db pull --force --url mongodb+srv://prisma:[e-mail]/test?retryWrites=true&w=majority
Prisma schema loaded from prisma\schema.prisma
Environment variables loaded from .env
Datasource "db"

Introspecting …

✔ Introspected 1 model and wrote it into prisma\schema.prisma in 3.63s

Run npx prisma generate to generate Prisma Client.

This is really bad on Windows, and we should really figure out if there is some good guidance we can give Windows users. They will really hate using MongoDB from Windows (as I just do while I am reproducing a few older issues).

Update, we tested the workaround mentioned via the links above: Before: ✔ Introspected 3 models and wrote them into prisma\schema.prisma in 125.38s After: ✔ Introspected 3 models and wrote them into prisma\schema.prisma in 5.34

Figuring out the details next.
