This blog was originally published in August 2018 and was updated in May 2023. Hardware optimization : You need to ensure that the CPU, memory, and storage components meet the performance requirements of the database workload. This parameter sets how much dedicated memory will be used by PostgreSQL for the cache.

This post at an entry-level discusses the options you have to improve log throughput in your benchmark environment. . To illustrate the data reads on Oracle we can flush the buffer cache. Consequently we now need to increase the buffer cache in size if we are to see more CPU activity. so what are your options? PostgreSQL.

As an engineer on a browser team, I'm privy to the blow-by-blow of various performance projects, benchmark fire drills, and the ways performance marketing (deeply) impacts engineering priorities. With each team, benchmarks lost are understood as bugs. Chrome has missed several APIs for 3+ years: Storage Access API. Pointer Lock.

A then-representative $200USD device had 4-8 slow (in-order, low-cache) cores, ~2GiB of RAM, and relatively slow MLC NAND flash storage. India became a 4G-centric market sometime in 2018. The Moto G4 , for example. 2] Getting accurate global information that isn't artificially reduced to averages remains an ongoing challenge.

Budgets are scaled to a benchmark network & device. Deciding what benchmark to use for a performance budget is crucial. Simulated packet loss and variable latency, however, can make benchmarking extremely difficult and slow. Time required to read bytes from disk (it’s not zero, even on flash-based storage!).
