Where aws ends and the internet begins is an exercise left to the reader. After tuning our store for Pushy’s needs, it has been on autopilot since, appropriately scaling and serving our requests with very low latency. This delicate balance led to us doing a deep evaluation of many instance types and performance tuning options.

In addition, DynamoDB Accelerator (DAX) a fully managed, highly available, in-memory cache further speeds up DynamoDB response times from milliseconds to microseconds and can continue to do so at millions of requests per second. Auto Scaling is on by default for all new tables and indexes.

Tune the random_page_cost parameter. Tune the effective_cache_size parameter. Next is the table definition. I included a sequence creation statement for the id column since one best practice is always to have a primary key column, but for the specific examples we will go through, we don’t need it.

Instead, focus on understanding what the workloads exercise to help us determine how to best use them to aid our performance assessment.

So when their compiled application sends ad hoc queries to SQL Server, particularly as a prepared statement, and when we don't have the freedom to add or change indexes, several tuning opportunities are immediately off the table. You won't be able to check the plan cache for these results, because of the recompile. TheThings. (

A co-worker introduced me to Craig Hanson and Pat Crain's performance mantras, which neatly summarize much of what we do in performance analysis and tuning. sounds like a homework exercise of purely academic value. They are: **Performance mantras**. Don't do it. Do it, but don't do it again. Do it less. Do it later. Do it concurrently.
