These have inspired me to summarize another performance activity: evaluating benchmark accuracy. Accurate benchmarking rewards engineering investment that actually improves performance, but, unfortunately, inaccurate benchmarking is more common. If the benchmark reported 20k ops/sec, you should ask: why not 40k ops/sec?

So, we pitted the two connection poolers head-to-head, using the standard pgbench tool, to see which one provides better transactions per second throughput through a benchmark test. All of the PostgreSQL benchmark tests were run under the following conditions: Initialized pgbench using a scale factor of 100. Throughput Benchmark.

Google’s industry benchmarks from 2018 also provide a striking breakdown of how each second of loading affects bounce rates. It’s inherently tied to everything we build and develop. I’m going to update my referenced URL to the new site to help decrease latency that adds drag to the initial page load. Let’s trim that down.

The presentation discusses a family of simple performance models that I developed over the last 20 years — originally in support of processor and system design at SGI (1996-1999), IBM (1999-2005), and AMD (2006-2008), but more recently in support of system procurements at The Texas Advanced Computing Center (TACC) (2009-present).

Here’s some predictions I’m making: Jack Dongarra’s efforts to highlight the low efficiency of the HPCG benchmark as an issue will influence the next generation of supercomputer architectures to optimize for sparse matrix computations. In early January a related paper was published by Satoshi Matsuoka et. petaflops, which is 0.8%

Apple forces developers of competing browsers to use their engine for all browsers on iOS , restricting their ability to deliver a better version of the web platform. They are, pound for pound, some of the best engine developers globally and genuinely want good things for the web. With each team, benchmarks lost are understood as bugs.

Likewise, object access paths must be heavily multi-threaded and avoid lock contention to minimize access latency and maximize throughput. During load-balancing, the client gets the following exception when accessing the cache: ErrorCode<ERRCA0017>:SubStatus<ES0006>:There is a temporary failure. Please retry later.

A then-representative $200USD device had 4-8 slow (in-order, low-cache) cores, ~2GiB of RAM, and relatively slow MLC NAND flash storage. Meanwhile, developer behaviour offers little hope: Median mobile JavaScript payloads have only grown since 2016, now hovering above 400KiB of script transferred, or nearly 2.5MiB of uncompressed JS.

One of the most surprising results has been the frequent occurrence of “ambush by JavaScript” : We need a new term for the business-opportunity wastage that modern front-end development has created. Budgets are scaled to a benchmark network & device. Deciding what benchmark to use for a performance budget is crucial.

The L3 cache size is 64MB. I wrote about using CPU-Z to benchmark the Intel Xeon E5-2673 v3 processor in an Azure VM in this article. Figure 1: CPU-Z Benchmark Results for LS16v2. The L3 cache size is 64MB. They feature low latency, local NVMe storage that can directly leverage the 128 PCIe 3.0 Azure Lsv2 Details.

Stable media is commonly physical disk storage, but other devices and certain caching facilities qualify as well. Many high-end disk subsystems provide high-speed cache facilities to reduce the latency of read and write operations. This cache is often supported by a battery-powered backup facility.

In many organizations, front-end developers know exactly what common underlying problems are and what loading patterns should be used to fix them. So every time a conversation about further development happens, performance is a part of that conversation as well. Establish a performance culture. thanks, Guy Podjarny!
