Houdini RS Very slow startup (path mapping?)

Hi, I’ve been using Deadline for a while now, but for some reason the current project has very slow startup times. I’ve already set it up such that each task renders 15 frames, that way I suffer the slow startup only once every 15 frames - it is still annoying though.

It happens on both my worker machines, and according to the job report the time is lost in path mapping. I haven’t set anything up regarding this, don’t even know what it is exactly, and it hasn’t been a problem in other jobs, not that I would have noticed. Example log (8 minutes lost):
