Slow export in Final Cut Pro

Hello again,

I tried to figure this out on my own but I can't wrap my head around it.

Everything works great, the only issue that I see is the export times of the video files I edit in Final Cut, at first I thought it might be from the processor but its on 80%, so I checked the disk usage and I see spikes from 0kb/s to 10mb/s and back and forth. For 2 seconds I have 10mb/s and the next one is 0, not to mention that 10mb/s is extremely low.

Bsically for a 2 minutes 4K clip with no transitions, just some luts its taking over 6 minutes to finish.

I tested the disk with Aja and the results for my nvme are 1700/1800 W/R. Anybody else encountered this?
