@techknowlogick why ? does it failed during CI ? Because the goal was mainly to keep track of performance between releases.

[techknowlogick]

@sapk yes, it fails on the migrate benchmark. I think we should wait until we migrate to Drone 1.0.0 to resolve this so we can have a separate benchmark pipeline and have that run on a dedicated machine as well.

Create an issue for that is better so that we will not forget that.
