OK, done.
In fact, with 10000 mobiles masses and 10000 fixed masses, if i want
position of the mobiles masses, i need to use a list split with
10000*2=20000 (for X and Y).

So i have something like this :
[MSD2D]
|
[route massesPosL]
|
[list split 20000]
|
[t l l]
|     \
[list length]
|       \
[until]  \
|         \
[list append]
|         /
[list split 2]
|
[unpack f f]
|
etc. with gemhead

Maybe i miss something, but even with a structure with 2500 mobiles
masses, this is slow.
Thanx for your help.
