There are a number of benchmarks that come with Amber: jac (23,000 atoms),
hb (about 40,000 atoms), factor_ix (about 91,000 atoms), rt (about 140,000
atoms.) Any of these can be made to run longer by simply increasing the
number of md steps.
The "dhfr" benchmark only differs in minor ways from jac. Take a look at the
benchmarks link at the Amber web site for more information. Also, note that
for solvated periodic simulations, pmemd will (always or almost always)
outperform sander, and is the recommended program for problems that it can
handle.
