At some point you'll be given permission to "focus on performance" and after many more hours, the website will be fast again. What if there was a way that you could prevent performance from degrading in the first place? Some sort of performance gateway that only allows changes to production code if they meet performance requirements?

It is the shared storage that often causes performance issues for data bases which are otherwise separated across nodes. In such a case we have a Bandwidth heavy workload profile (reporting) sharing with a Latency Sensitive workload (transactional). The key thing to observe is the impact on the latency sensitive (OLTP) workload.

In that scenario, the system would need to deal with the data propagation latency directly, for example, by use of timeouts or client-originated update tracking mechanisms.

Since we were optimizing at the logging level for storage and performance, we had less data and metadata to play with to optimize the query performance. Eventually, we decided to simplify the logger.

While there is plenty of well-documented benefits to using a connection pooler, there are some arguments to be made against using one: Introducing a middleware in the communication inevitably introduces some latency. A middleware becomes a single point of failure. They are well worth the added configuration and maintenance effort.
