Hey Ludo,

I haven't tried it yet. I think that the real bottleneck was having N fibers fighting over 4 workers to execute large number of insertions. Having all those queries done by workers dedicated to registration in a single pass seems to improve a lot the situation. Maybe having those registration workers posting unique transactions containing all the queries would be even more beneficial. Thanks, Mathieu
