Issue

At least *10 performance reduction in poetry export

After trying to find out why my build CI/CD stage went from 40 secs to 7 minutes without any reason, I found out that the version 1.4.0 has huge impact on the speed of the command: poetry export -f requirements.txt
I do also have an up todate poetry.lock file next to the pyproject.toml if it can have an impact.

I'll have to switch back to old poetry version.
