Although both countries are relatively close to one another, they are separated by a distance of approximately 500km, which adds up in terms of latency. As of 2016, there were just over 5.1 Before the implementation of our Helsinki POP, Finnish users were delivered content from our POP in Stockholm, Sweden. penetration rate.

Because HTTP redirection is handled server-side, it is typically faster than client-side redirection, especially if the browser can cache the new location of the requested file. Originally published September 2016, updated July 2019. Using JavaScript Redirection. Keep in mind that all of these methods add time to your page loads.

I started writing “ Serverless Architectures ” in May 2016. I was a little restricted in my thinking the first time around and I’ve come to see FaaS as something not quite stateless, since caching state in a Lambda instance that might stick around for 5 hours is a perfectly reasonable idea. I thought a few folks might be interested.

Redirects are often pretty light in terms of the latency that they add to a website, but they are an easy first thing to check, and they can generally be removed with little effort. I’m going to update my referenced URL to the new site to help decrease latency that adds drag to the initial page load. Text-based assets.

Add to this the fact that desktop devices have a lifespan between five and eight years, on average, and that the P75 device was sold in 2016. That is, what was the average device in 2016? These devices feature: Eight slow, big.LITTLE ARM cores (A75+A55, or A73+A53) built on last-generation processes with very little cache.

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. A then-representative $200USD device had 4-8 slow (in-order, low-cache) cores, ~2GiB of RAM, and relatively slow MLC NAND flash storage.

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 ). Here I assumed a particular analytical function for the amount of memory traffic as a function of cache size to scale the bandwidth time.

The image below shows a significant drop in latency once we've launched the new point of presence in Israel. In fact, latency has been reduced by almost 50%! With a total of 5 POPs in Oceania, this continent benefits from lower latency with every POP added. With a population of 2.5

At the time of the last Confluence run, the gap had stretched to nearly 1000 APIs, doubling since 2016. For heavily latency-sensitive use-cases like WebXR, this is a critical component in delivering a good experience.

The L3 cache size is 64MB. The slightly newer Intel Xeon E5-26xx v4 (Broadwell) series which was introduced in Q1 of 2016, increased that to 2400MHz. The L3 cache size is 64MB. They feature low latency, local NVMe storage that can directly leverage the 128 PCIe 3.0 lanes for I/O connectivity. lanes per processor.

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.

It simulates a link with a 400ms RTT and 400-600Kbps of throughput (plus latency variability and simulated packet loss). Simulated packet loss and variable latency, however, can make benchmarking extremely difficult and slow. Our baseline, then, should probably trade lower throughput/higher-latency for packet loss.
