Understanding the system log (boot time 2 minutes)

Question

Dear Apple Discussion,
I am trying to read the system.log correctly - mainly because my boot time is 2 minutes.
I have read that the beginning of the boot up is indicated by the line:
localhost kernel[0]: standard timeslicing quantum is 10000 us
is this correct?
Next, does the line:
loginwindow[165]: Login Window Started Security Agent
indicate that the login window has come up?
If both of these are correct then my boot time should be 18s (according to the time stamps in the log) - it defefinitely is not that.
Does the boot process start instead at this line:
shutdown: reboot by root:
If this were the case, the boot time would be closer to 2 minutes according to the log (which is what it actually is).
This then brings up the next problem: the two minutes basically come from the following line:
Nov 29 17:30:24 Purrfekt shutdown: reboot by root:
Nov 29 17:30:24 Purrfekt SystemStarter[177]: authentication service (194) did not complete successfully
Nov 29 17:30:24 Purrfekt kernel[0]: CiscoVPN : unloading cisco ipsec kernel module.
Nov 29 17:30:24 Purrfekt kernel[0]: CiscoVPN : detaching from interface: en1.
Nov 29 17:30:24 Purrfekt kernel[0]: CiscoVPN : interface en1, filter has been safely detached.
Nov 29 17:30:24 Purrfekt kernel[0]: CiscoVPN : detaching from interface: en0.
Nov 29 17:30:24 Purrfekt kernel[0]: CiscoVPN : interface en0, filter has been safely detached.
Nov 29 17:32:12 localhost kernel[0]: standard timeslicing quantum is 10000 us
ending line of the boot process occurs at (if my above assumption is correct):
Nov 29 17:32:31 Purrfekt loginwindow[165]: Login Window Started Security Agent
So why does it hang for so long at this one process? Am I reading the log incorrectly? I have searched around here and also on google ("slow boot time", "cisco vpn tiger", etc..) but haven't found anything relating to my problem.
Thanks for any help.

I am trying to read the system.log correctly - mainly because my boot time is 2 minutes.
It appears to be that a restart or shutdown process delays nearly 2 minutes rather than a startup process, presumably due to one of WindowServer children or a bug stays in Mac OS X 10.4.3 Update-- Mine delays approximately 30 - 40 minutes on PowerMac G5 2.7 Ghz on every shutdown or restart process. Your computer is PowerMac G4 so that make sense. I found a suspect application which is a security related. Although I am still investigating further because the issue does not occur on the lower drive bay where I install another Mac OS X 10.4.3 Update (but no third-party software) as a test facility.
localhost kernel[0]: standard timeslicing quantum is 10000 us
This is correct and the first line to display sequential events in a boot process.
loginwindow[165]: Login Window Started Security Agent
This is also a normal behavior.
SystemStarter[xxx]: authentication service (xxx) did not complete successfully
This can be displayed depending on a computer configuration.
A sequential event from CiscoVPN: unloading cisco ipsec kernel module to CiscoVPN: interface en0, filter has been safely detached seems to be all right if you PROPERLY configure VPN policy and IPsec (Internet Protocol Security) authenticate, etc for your Cisco device. IPsec is a framework for a set of protocols for security at the network or packet processing layer of network communication.
I suggest to check all related settings with Netwrok/Sharing panes and the router configurations for VPN (IPsec), IPv6, security, etc. Also check routing table and all socket connections after you launch Network Utility or via Terminal commands.
FYI: interface en0 is a wired connection and interface en1 is a wireless connection such as AirPort. IPsec kernel module is a unit of kernel program or componet for IPsec.
Hope this helps.
