Running $p->N_LATTICE_POINTS using Latte is very slow on my installation (polymake 2.13).
I wrote a simple perl script timing Latte's <i>count</i> command on the polytope:
[[1,0,0,0],[1,0,0,7],[1,0,7,0],[1,7,0,0]]
RESULT:
120
TIME: 0 wallclock secs ( 0.00 usr + 0.00 sys = 0.00 CPU)
Running a timer on $p->N_LATTICE_POINTS returns:
TIME: 1 wallclock secs ( 0.88 usr 0.01 sys + 0.01 cusr 0.01 csys = 0.91 CPU)
(This is consistent over repeated runs, and there are similar results for running both latte 1.7.1 and latte 1.6)
Is there some heavy overhead for running Latte from within polymake, or might there be some kind of problem with my configuration?
