When deciding what to pick, there are many things to consider, like where the proxy needs to be, if it “just” needs to redirect the connections, or if more features need to be in, like caching and filtering, or if it needs to be integrated with some MySQL embedded automation. Given that, there never was a single straight answer.

Compute optimized – High CPU-to-memory ration, medium traffic web servers and application servers. Memory optimized – High memory-to-CPU ratio, relational database servers, medium to large caches, and in-memory analytics. Benchmark Test. For a real production test, this should be large enough to help avoid hitting cache.

A then-representative $200USD device had 4-8 slow (in-order, low-cache) cores, ~2GiB of RAM, and relatively slow MLC NAND flash storage. Using a global ASP as a benchmark can further mislead thanks to the distorting effect of ultra-high-end prices rising while shipment volumes stagnate. The Moto G4 , for example.

Load balancing : Traffic is distributed across multiple servers to prevent any one component from becoming overloaded. Load balancers can detect when a component is not responding and put traffic redirection in motion. Each node has its own cache buffer.) That means having a primary system and a secondary system.

To show that I can criticize my own work as well, here I show that sustained memory bandwidth (using an approximation to the STREAM Benchmark ) is also inadequate as a single figure of metric. (It Here I assumed a particular analytical function for the amount of memory traffic as a function of cache size to scale the bandwidth time.

Budgets are scaled to a benchmark network & device. Deciding what benchmark to use for a performance budget is crucial. Contended, over-subscribed cells can make “fast” networks brutally slow, transport variance can make TCP much less efficient , and the bursty nature of web traffic works against us.

Synthetic monitoring actively allows users to monitor the performance of their website or application with a set of controlled variables (geography, network, device, browser, cached vs. uncached) over time.

Efficient memory management, including optimizing query caches and buffer pools, can help strike the right balance between memory consumption and query response times. Key parameters like the buffer pool size significantly impact efficiency by determining how much data MySQL can cache in memory for rapid access.
