Recommended "vm_compressor=2" or "vm_compressor=4".
Compressor mode 4 (VM compressed + swap) and all the steps between 1st-4th descripted before, is equal than compressor mode 2 (VM compressed/encrypted without swap).
In compressor mode 1, if you disable swap, system is always 100% memory pressure, and if memory is full at some point, the system will freeze.
So i recommended mode 2 or 4 with steps to disable swap applied.
