Slow post job cleanup

[Tanguille]

I've been using this action with success for months but I've noticed in my last few runs that the post job cleanup task takes as much or more time then compilation itself.
I wonder if I'm the only one experiencing this issue and what I could do to resolve it.

This is the output of the post job cleanup task:

Post job cleanup.
