My personal opinion is that I don't see a widespread need for more capacity given horizontal scaling and servers that can already exceed 1 Tbyte of DRAM; bandwidth is also helpful, but I'd be concerned about the increased latency for adding a hop to more memory.

A close monitoring of the hardware enthusiast community, including many of the most respected hardware analysts and reviewers paints an even more dire picture about Intel in the server processor space. Despite all of this, Intel is not going to lose their entire server processor business any time soon.

I summarized these topics and more as a plenary conference talk, including my own predictions (as a senior performance engineer) for the future of computing performance, with a focus on back-end servers. This was a chance to talk about other things I've been working on, such as the present and future of hardware performance.

This post was originally published in June 2020 and was updated in September 2023. This results in expedited query execution, reduced resource utilization, and more efficient exploitation of the available hardware resources. An improperly configured server may not allocate sufficient resources or be optimized for the specific workload.

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.

2015-2020: Overhead As part of production rollout I did many performance overhead tests, which I've described publicly before: The overhead of adding frame pointers to everything (libc and Java) was usually less than 1%, with one exception of 10%. Back-end servers. The actual overhead depends on your workload.

Resources can be any element i.e., hardware, software, or infrastructure which are necessary to carry out tests. This is due to the fact that the cloud enables the provisioning of test servers on demand. This also ensures unused servers are not sitting idle. In 2020, the total worth of the cloud market was $371.4

The answer is hardware interrupts. The interval between timer interrupts depends on the Windows version and on your hardware but on every machine I have used recently the default interval has been 15.625 ms (1,000 ms divided by 64).

The issue with that is that they’re always sent to your server, even if one of your users clicks on a GET request URL on someone else’s website and that GET request has side effects you or your user won’t like.

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.
