This rough idea is the basis of A Fire Upon the Deep by Vernor Vinge. It has this idea of "zones of thought" where there's basically a speed limit on the speed of thought and advanced civilizations move up into the higher zone with a faster limit. It's an incredible book and well worth the read.

It's one of my favorite books. For those of us that came of age during the golden age of Usenet, there are a ton of jokes related to the communication throughout the galaxy. Because communication is so slow, it resembles Usenet, with it's relays, etc.

The AI stuff in the book is also really interesting.

Also, let's not forget that Vinge coined the term singularity.
