Is it? It starts pretty fast for me.
purge-db4o will also alleviate this even more.
You should admit that the last time I talked to you about this, you said you
were running Freenet on a Pentium 4. Those have not been produced any more for
6 years!
And from my personal experience of helping a lot of average PC users with
computer problems, I can tell you that I would guess >90% of average-guy PCs
are Core 2 and above. I cannot even remember when I was asked to repair a P4
the last time.
And I would say that most Core 2s are also getting replaced by Core i's this
xmas, as browsing with a Core 2 is horribly slow due to the general feature
creep of modern web development.

Again from general computer repair experience, I can tell you that *no*
average PC will start fast. People usually have 10+ tray icons.
It doesn't matter to them: They typically use standby or hibernation, as it
has even been the default action for the "power" button the Start menu for
years. Reboots only happen if they're forced to by updates.
Most people I know don't even do any shutdown action when they leave their
home - all they do is shut the lid of their laptop, and let it do whatever it
wants to.

The primary concern *for* doing this is that Freenet *needs* high uptime:
- to prevent correlation attacks ("During the 5 minutes it usually takes to
insert Freesite X, Node Y is always online. During the remaining hours of the
day, it is always offline"). Those are very easy attacks! You don't have to
write special code to walk the network in a complex way, you only need a high
performance node which connects to very many peers and logs their node
identity.
- to improve performance as announcement is slow. This is a huge usability
issue as it can take half an hour to connect after startup!
- to provide the stored data to the network. We're a storage network, and data
falling out is always a problem. Its better if we have many high uptime nodes.
