Per above, the Win 94 is a great rifle and can operate quickly but by virtue of its pivoting linkage action design, its never going to feel like a Marlin or Henry (rotating on a single point). In fact, I would say the Win 94 must be handled with some vigour to reliably feed since the lifter moves up at the end of the downward stroke.
Without knowing what the specific symptoms of jamming are, questions to be ask may incl the fol:
-Does this happen only when firing live rounds?
-Does this happen when using dummy dry fire rounds?
-Does this happen if the hammer is manually cocked prior to cycling?
-When the bolt and receiver rails are cleaned/lubed, does this still occur?
-Have you checked the extractor claw and recess?
