I never meant it to be a `benchmark' of system performance, though I did
ask whether it relates to kernel performance since visibly both systems
appeared to reach the same state but took vastly different times.

There are two OSes dealing with same hardware with remarkable difference
in time to initialize it. It's a matter of curiosity and technical
interest to know whether I could tweak one to do better.

Thanks to a few responses so far, I got to understand about how timeouts
can influence.

No. I haven't come across such a thing before. Could you please suggest
something more to read / try? (Will also search.) Thanks for the input.
