Running speed tests with tools like Google PageSpeed Insights , WebPageTest , or KeyCDN’s Website Speed Test are always a good way to help gauge your website’s performance. That’s why Google created a performance revenue calculator that estimates how much additional revenue you could be making if your site was faster.

SQL Performance

JULY 16, 2019

For many years, I explicitly advised people not to run their SQL Server workloads on AMD hardware because of the much lower single-threaded CPU performance and consequently higher SQL Server core license costs. This has led to a very noticeable reduction in generational performance increases since Broadwell-EP, as shown in Figure 1.

Some time ago I participated in design of a backend for one large online retailer company. The rationale behind these methods is that frontend should be able to fetch transient information very efficiently and separately from fetching of heavy-weight domain entities because this information cannot be cached.

In traditional row-mode execution plans, SQL Server may introduce a Bitmap operator as part of performing early semi join reduction before a parallel hash or merge join. The SQL Server batch mode implementation of a Bloom filter is optimized for modern CPU cache architectures and is known internally as a complex bitmap. Background.

With their tightly integrated client-side caching, IMDGs typically provide much faster access to this shared data than backing stores, such as blob stores, database servers, and NoSQL stores.
