Even if it is 4G (5G, or whatever else) that doesn’t exactly guarantee you’ll be getting the amazing, theoretical speeds promised. While they technically do state in the description of the technology that it’s not 5G, they still call it 5G E and display it as such on your phone if you connect to it.

This is a complex topic, but to borrow from a recent post , web performance expands access to information and services by reducing latency and variance across interactions in a session, with a particular focus on the tail of the distribution (P75+). Consistent performance matters just as much as low average latency.

Using a global ASP as a benchmark can further mislead thanks to the distorting effect of ultra-high-end prices rising while shipment volumes stagnate. Recall that single-core performance most directly translates into speed on the web. Today, either method returns a similar answer. Tap for a larger version. How bad is it?

Most partners we work with are not aware of the real-world operating environment and make inappropriate technology choices as a result. Budgets are scaled to a benchmark network & device. JavaScript is the single most expensive part of any page in ways that are a function of both network capacity and device speed.

Performance issues surrounding Availability Groups typically were related to disk I/O or network speeds. Our customers who deployed Availability Groups were now using servers for primary and secondary replicas with 12+ core sockets and flash storage SSD arrays providing microsecond to low millisecond latencies.

You need a business stakeholder buy-in, and to get it, you need to establish a case study, or a proof of concept using the Performance API on how speed benefits metrics and Key Performance Indicators ( KPIs ) they care about.

This difference has substantial technological implications, from the classification of what’s interesting to transport to cost-effective storage (keep an eye out for later Netflix Tech Blog posts addressing these topics).

Many high-end disk subsystems provide high-speed cache facilities to reduce the latency of read and write operations. This allows the checkpoint process to maintain its speed while the random nature of the I/O requests deters any elevator seeking that could ​​ affect ​​ other I/O operations.

​​ The larger sector sizes involve newer technology and require API changes at the operating system level. The caching of data pages and grouping of log records helps remove much, if not all, of the command latency associated with a write operation.
