[postgis-users] Best projection srid for topology

Hello all,
I'm working on a many million lines topology project with OSM data in 4326 srid. I'd like to know if i should transform their geom in a meter srid ( like 3857). Should it be faster for the 'toTopoGeom()' function to work with geometry in 4326 or in 3857 srid?
Thanks

Marc
