Back in 2016, I gave a talk outlining the causes and effects of the terrible performance of web apps built using popular tools on the fastest-growing device segment: low-end to mid-range Android phones. Modern network performance and availability. The cheapest (high volume) Androids perform like 2012/2013 iPhones, respectively.

” This paper describes a “far memory” system that has been in production deployment at Google since 2016. This boils down to a single digit µs latency toleration in the tail for far memory, and in addition to security and privacy concerns, rules out remote memory solutions. Enter zswap! Evaluation.

Recently one of our teams was investigating a log reader latency issue. We pay a lot of attention to latency here, along with any long-running transactions, because of downstream impact to technologies that use the log reader – like Availability Groups and transactional replication.

This was a keynote presentation at the “2nd International Workshop on Performance Modeling: Methods and Applications” (PMMA16), June 23, 2016, Frankfurt, Germany (in conjunction with ISC16 ). Over time, the mechanisms introduced for reducing energy consumption (first in laptops) became available more broadly.

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.

These VMs are not available in all regions, so you will want to check the availability in the Azure region that you are interested in using. As 128GB DDR4 DIMMs become more widely available that total capacity will double. They feature low latency, local NVMe storage that can directly leverage the 128 PCIe 3.0

By 2021, a distributed cloud would help companies physically put all services closely together, thereby addressing low-latency challenges, minimising the expense of storage and ensuring that data standards are consistent with the laws in a given geographical region. In 2021 what can we expect?

In the latest (October 2016) revision of Intel’s Instruction Extensions Programming Reference , Intel has disclosed a fairly dramatic departure from these “traditional” approaches. With 2 FMA units that have 5-cycle latency, the code must implement at least 2*5=10 independent accumulators in order to avoid stalls.
