What problem are you facing?

Signifikant performance regression (~20%) for simple Find-Queries after Node-Version-Upgrade.

What driver and relevant dependency versions are you using?

MongoDB-Version: 4.2
MongoDB-Node-Driver: 4.9.1

NodeJS-Version: 16.15.1
NodeJS-Version: 18.8.0

Steps to reproduce?

See attached simple file.
-> Create some data (it seems like count is more important than size of the documents)
-> Execute simple Find-Queries

My times from the attached file:
Node16:
async iteration: 2.144s
toArray: 2.080s

Node18:
async iteration: 2.606s
toArray: 2.493s
