You can't run one nxagent on multiple cores, as it is
single-threaded. You can of course have one user's nxagent on one core
and another user's nxagent on another core (this will be done
automatically by the OS scheduler).

If you have a single user who needs more performance, your only option
is to beef up the CPU--or find a less brute-force approach to solving
the problem.

For example, what sort of 3D application is it? Is it using GL? If it,
you could benefit greatly from using 3D graphics hardware. You might
like to look at chromium.
