Jon,
Have you figured out how to diminish that 'speed of light' issue, yet? My friend Einstein (a shaggier, white-furred fiend) and I, have been collectively experimenting with different algorithms... without much luck.

Actually, the speed of light has already been broken using quantum tunneling :

This will lead to quantum computing - which will in turn lead to processors being able to run at speeds almost infinitely faster than today's computers.
However, to expand on my original statements - to give a more in-depth description of what is occurring - and directly relate it to JDE....
Let's take a single sales order transaction of one line. Now this transaction in JDE usually takes about 1000 SQL statements to complete. Each SQL statement has to occur synchronously - ie, before the next statement occurs, the statement must usually finish. Most of these statements are READs as opposed to a handful of WRITEs
The speed of light travels at a constant 299,792,458 m / s. Over 20km, the time would therefore take Approximately 0.067ms to transverse the distance. Not very long.
However, 1000 SQL statements, providing each statement was contained in 2 packets (source -> destination and return packets) would therefore take 133ms to complete. That is assuming that every point along the path takes no time to transverse, ie, in a perfect, imaginary world.
The reality is that along each point in the 20km, there are a number of repeaters and other mechanisms that "translate" the data so that it can identify the destination. The longer the route, the more pieces used to route the traffic. Each point along the route adds an exponential amount of time for the processing. Since fiber can only realistically stretch 2km using traditional methods, it is realistic to imagine that there are at least 12 points along the route where traffic is slowed substantially.
A network specialist captures this data in millisecond timeframes, and can use tools to identify where traffic is being routed more slowly along the route, thereby explaining where your transaction is being slowed down...
It does appear, if you have a 27K fiber, and you bend it in half - that, wormhole affect is factually null and void. Now, if you bend it too far - and hear a 'snap', the wormhole affect is 'Completely Borked' - and you get absolutely now transmission. We did find, interesting enough, that if you cut that 27K fiber down to a few feet - life happens quicker!
We have come to the conclusion, that: a physically shorter distance creates a better performing speed of light.
