Finally, caching should not be a band-aid for general slowness. If some operation is unnecessarily slow, try to optimize it first, and ensure it is really needed. For example, I initially had the search index encoded as JSON, and it took ~600 ms to build and marshal it. I optimized it to only take ~10 ms. In the end, I realized I don't need a search index at all and removed all of this code. Do less, go faster.
