If it is just 5 devices, you might want to reserve IPs to each device in the dhcp server. But if you are curious enough you can use tcpdump to look at the actual negotiation and see what is the causing the delay. Depending on the dhcp server, it can take several seconds regardless of network activity or CPU speed.
This is because the server first queries the network to see if an address is in use before it offers it to a client, and it has to wait at least a little while for answers to arrive. This timeout is part of the delay you notice, and it will exist even on the quietest network. Your milage may vary. LazyBrush LazyBrush 7 7 bronze badges.
