The CMA may help here.

While looking at performance I implemented such thing. Result: very
small speedup. You just need to flush the cache too often:
 - everything which changes the happy state of the city (change of the
 citizen assigments, new trade routes, ...)
 - if government changes
 - if tiles on the city map changes
 - if city grows

So in short you have to invalidate the cache at least every turn and
maybe even multiple times a turn.
