Try whether it helps to use 64bit instead of 32 Avisynth, by setting "Config->Internals->Avisynth->Avisynth type" to "64bit".
In case you have an NVIDIA or Intel GPU you might also want to set "Config->Filtering->Avisynth->Libav hardware decoding mode".
Also enabling GPU in interframe might help to free some cpu ressources and speed things up.
+ Yes, UHD filtering especially Interframe is really slow.
+ Why are you treating the source as if it was TFF, it's progressive,...
+ Lowering the thread count ("Filtering->Avisynth->Misc->Scripts->Miscelleaneous->MT-Threads") to 2 seems to help a lot here, otherwise Avisynth seems to have issues handling the memory on UHD content. (works fine in Vapoursynth)
Cu Selur
Ps.: Depending on your system using Vapoursynth might be faster. + Source seems somehow causing
PPs.: I adjusted the Thread title.
