    The usual implementation of system is to load a command
    interpreter program, pass it the string you gave, then
    the command interpreter program must parse the string
    and then perform whatever action you specified, such as
    loading another program. All this loading and running
    new programs often does take quite a long time.

    You may find an non-portable implementation defined way
    that eliminates the command interpreter stage and starts
    your target program directly. That would be off-topic
    for comp.lang.c or comp.lang.c++.
