Thanks Peter. Is the difference in performance because in the global case a common 'largest step size' has to be used inside and outside the magnetic field, one which is too small for propagation of a particle in vacuum with no magnetic field?

If that's the case, I may have gotten around that by using a global field manager but changing the 'largest step size' to something small (0.1mm) when approaching the magnet and while inside the field and then changing the 'largest step size' to something relatively large (10m) as soon as the particle exits the magnetic field into vacuum with no field.
