High availability refers to the continuous operation of a database system with little to no interruption to end users in the event of system failures, power outages, or other disruptions. Fault tolerance refers to the ability of a database system to continue functioning in full, with no downtime, amid hardware or software failures.

In both cases, the OS will task the browser team to heavily prioritise integrations with the latest OS and hardware features at the expense of more broadly useful capabilities — e.g. shipping "notch" CSS and "force touch" events while neglecting Push. They certainly have leaders who understand the difference.

This enables the user to compare and contrast performance across different benchmark scenarios. The example has a configuration set to illustrate a number of wait events and has therefore not been configured for performance. The events are colour coded and indexed in the graph to the wait event groups. Workload running.

HammerDB is a software application for database benchmarking. It enables the user to measure database performance and make comparative judgements about database hardware and software. Databases are highly sophisticated software, and to design and run a fair benchmark workload is a complex undertaking. Derived Workloads.

I suggest it’s long past time to move beyond C and SPEC benchmarks and our exclusive focus on “metal” languages. There are already standard benchmark suites for JavaScript performance in the browser, and we can include applications written in node.js (server-side JavaScript), Python web servers, and more.

On August 7, 2019, AMD finally unveiled their new 7nm EPYC 7002 Series of server processors, formerly code-named "Rome" at the AMD EPYC Horizon Event in San Francisco. It will also use less power than a two-socket Intel server, with a lower hardware cost, and potentially lower licensing costs (for things like VMware).
