This post at an entry-level discusses the options you have to improve log throughput in your benchmark environment. . As HammerDB supports graphical metrics for Oracle, this provides the best illustration however the concepts apply in general terms to all databases. To illustrate the data reads on Oracle we can flush the buffer cache.

Many thanks to the engineers working hard to develop workarounds to these processor bugs. This overhead can be reduced by A) pcid, fully available in Linux 4.14, and B) Huge pages. - **Cache access pattern**: the overheads are exacerbated by certain access patterns that switch from caching well to caching a little less well.

The scale of the effect can be deeply situational or hard to suss out without solid metrics. A then-representative $200USD device had 4-8 slow (in-order, low-cache) cores, ~2GiB of RAM, and relatively slow MLC NAND flash storage. The Moto G4 , for example. Today, either method returns a similar answer.

Budgets are scaled to a benchmark network & device. This helps support executive sponsors who then have meaningful metrics to point to in justifying the investments being made. Very rarely have we seen a team succeed that doesn’t set budgets, gather RUM metrics, and carry representative customer devices.

” Here are additional metrics used to determine the reliability of a database, make adjustments that minimize downtime, and set benchmarks for meeting business continuity requirements. Each node has its own cache buffer.) Chaos engineering is designed to uncover unexpected, even shocking, surprises.

The primary metric for memory bandwidth in multicore processors is that maximum sustained performance when using many cores. This metric is interesting because we don’t always have the luxury of parallelizing every application we run, and our operating systems almost always process each call (e.g., Details in the next blog entry.)
