How to stabilize up/down and sideway movements best

I was testing brushless gimbal with Canon 5D II and 8-15 mm fisheye. It does its job extremely well stabilising the angular movements, but up/down, sideways and back/front movements are very visible as I was not walking that steady and the objects where very close. The stabilisation process takes very long on mac book pro 2010 so I thought to ask if anyone here would have tips what stabilisation settings would work best.

Here is a video directly from the camera;



this one has been stabilised with the automatic settings:



as have this one



With this later one I tried to make parts of the first part of the video faster, but as result, the stabilisation started always from the start and the result was that where the video was cut for speeding it up, there was jumps on the stabilisation. How could a continuos video clip that that has speed changes be smoothly stabilised?
