The MXF's are straight out of a Canon C300 which I think are AVC here is Premiere's property details.

I tried checking activity monitor during playback on the problematic machine and this is what I found:

Premiere's RAM usage stays at a consistent 9.06gb whilst playing back the MXF timeline. The software settings are such that it should allow Premiere to use up to 18gb of the machines 24gb if necessary so I'm nowhere near maxing out the RAM.

CPU usage jumps to around 80% for the first few seconds whilst playback is smooth then settles to around 23-25% when the footage is choppy and unwatchable, so again not maxing out the CPU.

The same machine under the same conditions plays back a raw red footage timeline smoothly with a consistent 40-50% CPU usage and around 4.5gb RAM usage.
