3 ns is orders of magnitude too short to draw any conclusions.  Simulate out to 
100 ns and we'll talk :)  I only say this because I know the APL can be 
reproduced with the settings I gave in CHARMM and GROMACS with very close agreement.

Yikes!  You're losing a ton of performance here (though check the log to make 
sure Verlet adjusted this to something more suitable).  Setting nstlist = 1 is 
only for energy minimization.
