ARP is used by TCP/IP to resolve an IP address such as
172.17.205.79 to a unique hardware address, 00:11:95:0b:cc:28
Communicates between two computers on the same subnet as the host
server.
You can improve the connection speed to a server used most often is
to make the static entry in ARP cache.
I'm not sure how you came to that conclusion. An ARP request/response
takes a very short time and generally happens only when the arp cache
expires for a given IP addresss. The timeout is usually measured in
minutes. If my memory is correct, it is only the ARP request for the
default gateway that happens periodically.
