There are problems like this that arise with large synchronous systems which lack reliable clocks - but one of the good things about machine intelligences of significant size will be that reliable clocks will be available - and they probably won't require global synchrony to operate in the first place.
I do remember reading that the brain does appear to have some highly regular pulse-like synchronizations in the PFC circuit. Every 33hz and 3hz if I remember correctly.
But that is really besides the point entirely.
The larger a system, the longer it takes information to move across the system. A planet wide intelligence would not be able to think as fast as a small laptop-sized intelligence, this is just a fact of the speed of light.
And its actually much much worse than that when you factor in bandwidth considerations.
I don't really know what you mean.
You think it couldn't sort things as fast? Search through a specified data set as quickly? Factor numbers as as fast? If you think any of those things, I think you need to explain further. If you agree that such tasks need not take a hit, which tasks are we talking about?
Actually, many of the examples you list would have huge problems scaling to a planet wide intelligence, but that's a side issue.
The space in algorithm land in which practical universal intelligence lies requires high connectivity. It is not unique in this - many algorithms require this. Ultimately it can probably be derived back from the 3D structure of the universe itself.
Going from on-chip CPU access to off-chip Memory access to disk access to remote internet access is a series of massive exponential drops in bandwidth and related increases in latency which severely limit scalability of all big interesting distributed algorithms.
