Redis stands for REmote DIctionary Server, created in 2009 by Salvatore Sanfilippo. Both Redis and Memcached are: NoSQL in-memory data structures Written in C Open source Used to speed up applications Support sub-millisecond latency In 2014, Salvatore wrote an excellent StackOverflow post on […].
Effective application development requires speed and specificity. Cloud providers then manage physical hardware, virtual machines, and web server software management. The FaaS model of cloud computing debuted in 2014 with startups like hook.io. Dynatrace news. Therefore, many organizations turn to function as a service.
These strange questions came to the fore back in 2014 when Netflix was switching services from CentOS Linux to Ubuntu, and I helped debug several weird performance issues including one I'll describe here. This server is spending about a third of its CPU cycles just checking the time! How long does it take to read the time?
I summarized these topics and more as a plenary conference talk, including my own predictions (as a senior performance engineer) for the future of computing performance, with a focus on back-end servers. Ford, et al., “TCP
Netflix headquarters circa 2014. The encoder can typically be improved years after the standard has been frozen including varying speed and quality trade-offs. Netflix interest in SVT-AV1 Reference software typically focuses on the best possible compression at the expense of encoding speed. 264 standard was finalized.
In this blog post, we will look at the lifecycle and release management for MySQL and MariaDB servers — where we are now and relevant historical background. Things were starting to significantly diverge back in 2014 when MariaDB 10 was released. It is worth noting both MySQL and MariaDB have Community and Enterprise versions.
Many were hesitant to sacrifice site speed for the added layer of security if they felt like they didn’t need it. Google made SSL use a ranking factor way back in 2014, and since Chrome 68, a “Not Secure” warning appears next to the URL of sites that aren’t using HTTPS. So what’s the truth? Is SSL slow?
My personal opinion is that I don't see a widespread need for more capacity given horizontal scaling and servers that can already exceed 1 Tbyte of DRAM; bandwidth is also helpful, but I'd be concerned about the increased latency for adding a hop to more memory. Ford, et al., “TCP

I've been teaching and writing about common SQL Server mistakes for many years. This article will expand on my previous article and point out how these apply to SQL Server , Azure SQL Database , and Azure SQL Managed Instance. SQL Server Agent alerts. This situation applies to on-premises SQL Server and IaaS. Statistics.
When we released Always On Availability Groups in SQL Server 2012 as a new and powerful way to achieve high availability, hardware environments included NUMA machines with low-end multi-core processors and SATA and SAN drives for storage (some SSDs). As we moved towards SQL Server2014, the pace of hardware accelerated.
Back in 2014, I wrote an article called Performance Tuning the Whole Query Plan. This follow-up post revisits the question for SQL Server 2019, using a larger number of rows. This machine has four i7 CPUs (hyperthreaded to 8) with a base speed of 2.4GHz. It has 32GB RAM, with 24GB available to the SQL Server 2019 instance.
A close monitoring of the hardware enthusiast community, including many of the most respected hardware analysts and reviewers paints an even more dire picture about Intel in the server processor space. Despite all of this, Intel is not going to lose their entire server processor business any time soon. So, what has changed my mind?

Devices and networks have evolved too: Alex Russell @slightlylate An update on mobile CPUs and the Performance Inequality Gap: Mid-tier Android devices (~$300) now get the single-core performance of a 2014 iPhone and the multi-core perf of a 2015 iPhone. Recall that single-core performance most directly translates into speed on the web.
These AMD EPYC processors have a number of advantages for SQL Server workloads, as I will explain in this article. This 14nm first-generation AMD EPYC 7551 processor has 32 cores and 64 threads, and it works in one or two-socket servers. This makes it a good choice for many SQL Server workloads, especially DW workloads.
SQL Server2014 SP2 and later produce runtime (“actual”) execution plans that can include elapsed time and CPU usage for each execution plan operator (see KB3170113 and this blog post by Pedro Lopes). SQL Server makes some timing adjustments in parallel plans to promote consistency, but they are not perfectly implemented.
My personal opinion is that I don't see a widespread need for more capacity given horizontal scaling and servers that can already exceed 1 Tbyte of DRAM; bandwidth is also helpful, but I'd be concerned about the increased latency for adding a hop to more memory. Ford, et al., “TCP
If you put your whole website on CDN, technically you don’t need a large number of server infrastructure and CMS licenses. They often get blindsided by vendor’s pitch and end-up making decision based on some fancy demos (see my post from 2014 on Adobe AEM ). Circa 2014, I was working with a big Japanese automotive brand in Australia.
Thus, the entire website development methodology benefits from the boosted speed and saves times by using these top front end frameworks. PWAs can save the time and efforts required to develop an entire native application for multiple platforms from scratch, hence speeding up the time to market and enhancing audience reach.
And here's an excerpt from [Linux] today (include/linux/sched/loadavg.h): #define EXP_1 1884 /* 1/exp(5sec/1min) as fixed-point */ #define EXP_5 2014 /* 1/exp(5sec/5min) */ #define EXP_15 2037 /* 1/exp(5sec/15min) */. Anyway, the following patch seems to make the load average much more consistent WRT the subjective speed of the system.
Oracle VM Server is based on Xen. Both Xen and KVM have had many performance and security improvements, and workloads can now be tuned to run at almost bare metal speeds (say, a 3% loss or less). Outside of EC2, many other providers are deploying on KVM. I also wrote and published an entertaining SMF manifest that played music.
Inferno JS would be your best option, if you would like to build client and server-side interfaces with faster speeds, better performance, and isomorphic rendering. . You will get add-ons like server-side rendering, routing and more. The DOM structure is surrounded by Inferno for browser/server edits. Inferno Pros.
Created by Evan You, Vue had its first public appearance in 2014. Two primary metrics verify the speed of an app: start-up time and runtime performance. Server-Side Rendering. As Google can adequately crawl JavaScript content nowadays, server-side rendering isn’t as necessary for SEO as before. Vue vs React: Performance.
How It Works: XEvent Output and Visualization SQL Server Management Studio Provides–“XE Profiler” Use the SSMS XEvent Profiler. Using SQL Server Management Studio (SSMS) and storing the events in a table requires reading the events, streaming to table storage followed by an order by event sequence query. The XEProfiler Sample.
This includes CDNs, proxy servers, and the like. Once the 60 seconds is up, the browser will head back to the server to revalidate the file. It means ‘do no t serve a copy from cache until you’ve revalidated it with the server and the server said you can use the cached copy’. public and private. Cache-Control: no-cache.
Virtualized in Hardware**: Hardware support for virtualization, and near bare-metal speeds. It's all a bit confusing, and I wrote about this in 2014: [Xen Modes]. When I joined Netflix in 2014, we had begun transitioning from PV to HVM (PVHVM). I'd expect between 0.1% This recommendation quickly became out of date.

The lower conversion rate on mobile could be due to a variety of reasons including the website not being responsive for mobile devices, the speed isn’t up to par, etc. Improve Site Speed In 2019, having fast site speed is imperative. There are many ways to speed up a slow website.
