Number of Particles; Exponent 2?

Hi All Gadget2 Users,

Does anyone know if deviation from power of two in base number of
particles have a meaningful effect on running time? From literature it
is quite obvious that most groups are using a base number of particles
that is exponent two (e.g. 512**3). However, when the number of
particles increases above, lets say, 1024**3 it would be nice to use
arbitrary number of particles for example 1500**3. Can anyone confirm
that there is no any additional delay when applying 1000**3 compared
to 1024**3 particles?
