Might be your Xeon chips, check to see if they have Intel Quicksync.
My system runs slow editing H264/H265 because no Intel Quicksync.
I can edit MXF Black Magic files, Prores just fine on my old beast.
My xeon's dont support quicksync.
I use h.264/h.265,braw and r3d
I noticed an interesting thing.
All values in the test are similar.
