Hi Manu, If the tristripper doesn't connect the triangles together well then it can result on few tristrips and lots of unconnected traingles that it has to put into a single list of triangles to avoid lots of separate primitive calls.
As to why your model is not being stripped well I can't say. We've used 3rd party code to do the tri-stripping so I'm not best placed to answer the low level questions, but... the original author of the cdoe Tanguy Fautre is now an OSG user and I believe still on the list so perhaps he'll be able to chip in ;-) Robert.
