what is the advantage of unix sockets?

i understood that there are several type of sockets: TCP, UDP & Unix.
i wondered, what is the performance advantages of unix socket of the other types?
isn't it equal to use UDP with localhost as destination over unix socket?

Thanks in advance,

udp - Internet user datagram protocol (UDP) SYNOPSIS
#include <sys/socket.h> #include <netinet/in.h> The following is the socket call for AF_INET sockets: s = socket(AF_INET, SOCK_DGRAM, 0); The following is the socket call for AF_INET6 sockets: s = socket(AF_INET6, SOCK_DGRAM, 0); DESCRIPTION
UDP is a simple, unreliable datagram protocol that is used to support the SOCK_DGRAM abstraction for the Internet Protocol family. UDP sockets are connectionless, and are normally used with the sendto() and recvfrom() functions, though the connect() function may also be used to fix the destination for future packets, in which case the recv() or read() and send() or write() functions may be used. UDP address formats are identical to those used by TCP. In particular, UDP provides a port identifier in addition to the normal Internet address format. Note that the UDP port space is separate from the TCP port space (that is, a UDP port may not be "connected" to a TCP port). In addition, IPv4 broadcast packets may be sent (assuming the underlying network supports this) by using a reserved "broadcast address"; this address is network interface dependent. There is no broadcast address in IPv6. Options at the IP transport level may be used with UDP; see the ip() reference page. ERRORS
If a socket operation fails, errno may be set to one of the following values: An attempt was made to create a socket with a port that has already been allocated. An attempt was made to create a socket with a network address for which no network interface exists. The socket is already connected. This error occurs when trying to establish connection on a socket or when trying to send a datagram with the desti- nation address specified. The system ran out of memory for an internal data structure. The destination address of a datagram was not specified, and the socket has not been connected. RELATED INFORMATION
