Do you mean to ask "why only one nginx process actually uses CPU"
instead? This usually means that nginx isn't really loaded and
one process is enough to handle all connections/requests.

In some situations you may want to disable accept mutex via

events {
accept_mutex off;
...
}

or tune it with accept_mutex_delay directive. This should result
in more even distribution of load between nginx processes.
