With the Information you give here, it's hard to give you specific
advice on how to speed up your simulations.
I found the following papers quite interesting and maybe they give you
some idea in how to improve the performance.
1. Larsson P, Hess B, Lindahl E (2011)
Algorithm improvements for molecular dynamics simulations.
Wiley Interdisciplinary Reviews: Computational Molecular Science 1: 93-108.
2. Larsson P, Lindahl E (2010)
A high-performance parallel-generalized Born implementation enabled
by tabulated interaction rescaling.
Journal of Computational Chemistry 31: 2593-600.
3. Bjelkmar P, Larsson P, Cuendet MA, Hess B, Lindahl E (2010)
Implementation of the CHARMM Force Field in GROMACS: Analysis of
Effects from Correction Maps, Virtual Interaction Sites, and Water Models.
Journal of Chemical Theory and Computation 6: 459-466.
