Thank's Cory. This made my about 60 % of the cpu time. But if you have a more aggresive solution, I'm interested !
In fact, I make a way in the streets, get a MultiLineString and have to find the shops around my way, let's say about 1 kilometers right and 1 kilometer left so I can really be more aggressive with the calculated way and even degrade it so I 'need' to erase every small 'right/left'.
