"On those infrequent occasions when you need to reboot Linux, you may find that the process takes longer than you'd like. Jack Wallen shares a number of tricks you can use to reduce boot times." While these tips are intended to shorten Linux boot times, some can also increase the security of your system. Speed and security in ten tips, both well-known and obscure.

On my systems it takes sometimes a few seconds to get an address, especially wirelessly. If it fails to get an address (for whatever reason), it may take 30 seconds or so before it gives up. Depending on the OS/Distro, if these task are done serially that can be a significant slowdown.
To me, the biggest speed-up is for most of these tasks to be done in parallel - thus our case of a failed dhcp request wouldn't matter.
Hmm, well, I haven't tried too many different distros but Mandriva does dhcp in the background and so does Ubuntu (not that I use the latter one..). The whole point is that _if_ it happens to take some time to get a response then the process can just idle in the background, it does not need to be blocking other services from starting up. Especially since it consumes virtually no CPU time.
