Problem Description
After upgrade from 3.6 to 4.2 (3.6 --> 4.0 --> 4.2), mongorestore allocates over 6GB ram and then start swapping. Consequently, restore is very slow (over 45 minutes instead of 7 minutes with mongo 3.6)
Steps to Reproduce
mongorestore \ --host localhost:27017 \ -u restore_user --authenticationDatabase "admin" \ -p <secret> \ --gzip \ --dir "${TMPDIR}/rs0/dump" \ --drop
