there's no doubt that the LTSP-5 in Ubuntu and Debian doesn't boot as fast as LTSP-4.2 did.
With LTSP-4.2, we spent an awful lot of time trimming things down as much as possible, which had a great effect on the boot speed. LTSP-5 is a complete re-design, and it hasn't had that fine tuning yet. But, believe me, at ever Ubuntu developer summit that we've been invited to (4 of them now), the speed of the boot has been high on my list of needing attention. I think Oliver has actually knocked about 30 seconds out of the boot time, but there's still more work needed. One of the things that I've noticed is the thin clients that have several USB ports are the ones that take a long time to boot. For instance, an HP5505 was taking about 2 minutes to boot, where a T-150 was taking only about 65 seconds. LTSP-5 is getting alot of our attention right now, and we'll continue streamlining it, to reduce the boot time and memory requirements.
