12. Optimization
• Push processing up to the front-end, make your users’ computers into a
distributed processing network. e.g. stream rendering
• Cache as much as possible, invalidate only when necessary.
• Sometimes features have to take a back-seat to performance/scalability.
• Look at profiler data.
• Watch query execution time, optimize when necessary with indexes,
partitions, de-normalization, etc.
• Know what your weak spots are and keep a close eye on them.
