Latency is (where I am used to it) a hard physical limit imposed on the upper end by the speed of light. When you have a system that literally spans a planet, there's only so much clever algorithms (and hardware) can do to speed up the time difference between "things happen in one end" to "things happen on the other".

Yeah, it is hard problem when you are hitting physics.

But then it really isn't a problem -- it is a limitation. Nothing you can do much about.

There are of course types of applications where latency is really tough topic. For one, low-latency trading is where companies are in arms race against other low-latency market players and there is always improvements form improving your product's latency.

But in a typical situation like websites and corporate services, the latencies required are so large that it is quite easy to reach them -- just don't do anything stupid.
