nobody can give meaningful advice on such vague information. you're
not saying whether you are using implicit or explicit solvent, what
force field, what MD settings, how you run NAMD, which binary and
version you are using and so on.

NAMD prints out some benchmark information during the run, which can
help to make an estimate.

there *always* is a choice.
