I think that in general it is faster to have more tables with ids as names.
 For very small data, searching through a single larger table might be
quicker than node access...but even then I doubt it.

For these data sizes more tables is probably faster.

(It should also be noted that in the more tables case, that data is
actually smaller, because you can eliminate the id column.)
