All of the SPECfp_rate2000 results were downloaded from www.spec.org, the results were sorted by processor type, and “peak floating-point operations per cycle” was manually added for each processor type. This includes all architectures, all compilers, all operating systems, and all system configurations.

This post is targeted towards the questions most often asked by non-technical management who want to get up to speed on what HammerDB is (what it isn’t) and how it can benefit their organization. HammerDB is a software application for database benchmarking. What is HammerDB? Why HammerDB was developed. Derived Workloads.

You will still have to maintain your operating system, SQL Server and databases just like you would in an on-premises scenario. Microsoft's Mine Tokus has a good article where she ran a series of scaled down TPC-E benchmarks against an E64s_v3 VM that was using the older Broadwell processor.

PostgreSQL performance optimization aims to improve the efficiency of a PostgreSQL database system by adjusting configurations and implementing best practices to identify and resolve bottlenecks, improve query speed, and maximize database throughput and responsiveness. Why is PostgreSQL performance tuning important?

on Myths and Legends of High Performance Computing  — it’s a somewhat light-hearted look at some of the same issues by the leader of the team that built the Fugaku system I mention below. HPCG is led by Japan’s RIKEN Fugaku system at 16 petaflops, which is 3% of it’s peak capacity. petaflops, which is 0.8% of peak capacity.

It ranks the world’s 500 most powerful supercomputers based on their performance as measured by the Linpack benchmark. FLOPS , or number of floating point operations per second, is a common measure of computer performance. The performance, R max , is measured by the Linpack benchmark with 64-bit floating point arithmetic.

Have you ever wanted to make these operations even slower? This weeks’ blog post covers a technique you can use to make all file operations on Windows run at one tenth their normal speed (or slower), in a way that will be untraceable for most users! And, of course, this post will also cover how to detect and avoid this problem.

SQL Server defines stable media as storage that can survive system restart or common failure. Many high-end disk subsystems provide high-speed cache facilities to reduce the latency of read and write operations. Torn pages generally arise after system outages where the subsystem does not complete the entire 8-KB I/O request.

Every front-end developer is chasing the same holy grail of performance: green scores in Google Page Speed. Real-life performance for your users and how the website “feels” when you’re using it should not be discounted, even if it costs you a point or two in Page Speed (otherwise, we would all just have a search bar and unstyled text).
