DHCP seems very slow ?

If I run a Linux DHCP server on my network a client with get a renew
in less then a second. My windows 2003 server (dual 3.2ghz, 4gb ram,
its just a DC/print server nothing else on it) running dhcp however
takes 5-10 seconds to give clients on the same switch an IP .. why ?

Shouldn't it be nearly instantaneous ? Computer says heres my MAC,
Server looks in its DB doesn't find the MAC so it issues a new IP in
its scope to said computer.

Why does Windows DHCP take so long ? Is there anyway to speed it up.

Windows DHCP does more. It will also sync the Client with the DNS Server if
the Clients's Record is out of sync or add the Client's records to the DNS
Server if they aren't already there. Linux DHCP does none of this.

Well that is true but it still shouldn't take so long .. and those
kind of things can be done in the background. The actual handing out
of an IP address should be near instant (less then 1 second) in
reality i think it should be under 100ms from request to responce.
5000 - 10000ms is a very long time in network time especially when we
are talking about equipment connected to the same physical switch.
