s_bsd.c:read_listener()
	max = 10;
#if defined(SLOW_ACCEPT)
        max = 1;
#endif
	while (max--)
        {

	}

If you raise that 10, it should accept clients faster.

Also note that if you require ident or something to connect that
your identd might decide to stop because it thinks it's under an
attack.
