Hardware virtualization for cloud computing has come a long way, improving performance using technologies such as VT-x, SR-IOV, VT-d, NVMe, and APICv. The latest AWS hypervisor, Nitro, uses everything to provide a new hardware-assisted hypervisor that is easy to use and has near bare-metal performance. I'd expect between 0.1%

Even if you render components on the server and hydrate them on the client, it still churns because component hydration is computationally expensive. When even a bit of React can be a problem on devices slow and fast alike, using it is an intentional choice that effectively excludes people with low-end hardware. I think JSX is great.

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. This is the second generation EPYC server processor that uses the same Zen 2 architecture as the AMD Ryzen 3000 Series desktop processors.

By Werner Vogels on 07 March 2013 08:00 PM. DynamoDB runs on a fleet of SSD-backed storage servers that are specifically designed to support DynamoDB. This allows us to tune both our hardware and our software to ensure that the end-to-end service is both cost-efficient and highly performant. All Things Distributed. Comments ().

SQL Server 2014 SP2 and later produce runtime (“actual”) execution plans that can include elapsed time and CPU usage for each execution plan operator (see KB3170113 and this blog post by Pedro Lopes). SQL Server makes some timing adjustments in parallel plans to promote consistency, but they are not perfectly implemented. TheYear , CA.

While Oracle remains the #1 database on the market, its popularity has steadily declined by over 18% since 2013. The $47,500 licensing costs for Oracle Enterprise Edition is only for one CPU core, that ultimately has to be multiplied with the actual number of cores on the physical server. What’s causing this massive shift?

In the end, it’s not the load events or server response times that define the experience, but the perception of how snappy the interface feels. It used to provide an insight into how quickly the server outputs any data. This knowledge will give you the best optimization target for ongoing efforts. What does it mean?

Is it worth exploring tree-shaking, scope hoisting, code-splitting, and all the fancy loading patterns with intersection observer, server push, clients hints, HTTP/2, service workers and — oh my — edge workers?
