This is a question that comes up quite often on another site I visit and the phrase that regularly surfaces on those occasions is 'info dump'. The general consensus is that necessary information needs to be spread out through the piece as required from helping the reader imagine a specific person to imparting the fact of ginger hair making your character behave like a stereotype (quick tempered)
But this is the first time I've seen it linked to pace. (see, told you it was worth discussing) And that's a valid point and useful too.
The problem is that I assume the average reader knowing as much about cyberpunks as I do. I also assume them having an idea of how a classic cyberspace or Matrix has been constructed. I also assume that the reader understand the meaning of the gene-manipulation and can draw conclusion from suttle hints that I have distriputed across the manuscript. By assuming these sort of things I have been able to write a novel, based on belief that the readers understand how certain things affects another ones. However, it is also the world building problem, as I do have to explain bit more about before I can settle on pure story telling and assume that the reader has enough of information to understand the actions, and therefore the story telling can evolve into quicker pacing.
Interesting point is that I have been recently reading Ms Rowlings books and I noticed that she writes in same way as I do, but she also dwell reader in longer descriptions of 'things and matters on the hand' and therefore those things extend the pace of how the story evolves.
When it comes to pace in the action, I have found that the reader can imagine more with less you write. Writer doesn't need to explain every move, or even whole action sequence, just important parts of it and the reader can imagine rest.
I use that sort of descriptive action with my 3rd person POWs through out the whole manuscript. The action is fast paced (short chapters, switching point-of-views), and the dialogue slower paced (centralised on the point-of -view character and the main story.)
The biggest problem on that sort of writing, is that one has be very strict on how to tell the story, and what the characters really know about the matters in the hand.
One editor who I talked about the matter suggested that instead of writing one book, I write five and then cut in all the best parts of those stories. I refused to do so, as a storyteller, I have to have an ability to keep the story in my mind and just tell what I want to the audience. Like many writing manuals say, is that one should only tell what is necessary, and rest can be taken as granted.
However that causes a problem on how much writer can assume on readers knowledge on the matter. Can one say that an average reader understand s on how cybernetics work? Can one assume that an average reader understand how cyberspace works?
The answer is no, not really, as one can never assume that an average reader has researched on the subject as much as you have done. Therefore the writer still have every single time write in enough of information to explain the unexplainable matters in the hand.
