Terraform parallelism flag doesn't work when running in Jenkins

Hi all,

I am running terraform refresh from Jenkins and it takes about 10m~ for a small state.
Trying to improve performance I ran the refresh local ony my computer with parallelism=60,
that improved to 3m~. When using the same config on Jenkins slave the running time stay 10m. Jenkins slave is not loaded on cpu/memory/network.

Any idea what I am missing?
