Web Performance Testing at YouTube
 
04:49
Even though YouTube operates at a scale of over a billion users per month, web performance testing follows the same core principles that you can apply to your own site. In this video, learn about how we measure the page load speed and how we instrument tests to make the experience even faster. We'll look at two front end performance testing methodologies: Real User Monitoring (RUM) with Client Side Instrumentation and synthetic testing with WebPagetest.

Performance Analysis Methodology
 
01:27:00
From LISA '12 Brendan Gregg, Joyent Performance analysis methodologies provide guidance, save time, and can find issues that are otherwise overlooked. Example issues include hardware bus saturation, lock contention, recoverable device errors, kernel scheduling issues, and unnecessary workloads. The talk will focus on the USE Method: a simple strategy for all staff for performing a complete check of system performance health, identifying common bottlenecks and errors. Other analysis methods discussed include workload characterization, drill-down analysis, and latency analysis, with example applications from enterprise and cloud computing. Don't just reach for tools—use a method!

Practical Performance: Understand the Performance of Your Application
 
44:41
This session discusses how you can maximize the performance of your application deployment with tools that are native to your server platform as well as cross-platform Java analysis and monitoring tools. The session begins with systematic steps you can take to locate a performance problem in a complex system and moves on to analysis you can do to understand the root cause of the problem. The picture is completed by consideration of the tools and techniques available to monitor application performance in normal operation so that you can catch performance issues before they build up into serious problems.

No matter how amazing your site is, website speed is critical to your website's success. Fast page loading leads to more conversions and overall better user experiences. Unfortunately most designers and developers only have the perspective of what's happening at the comfort of their lightning fast wi-fi connections. In order to get a realistic idea of how fast your website really loads for the end user, you can use Google Chrome's Developer Tools to get a better idea of how people with slow Internet experience your site. This is especially important if a large percentage of your target audience is living outside of the big city life, where Internet connections are usually much slower.

This session was presented at Sharkfest 2016, held at the Computer History Museum in Mountain View, California - June 13-16th 2016. www.packetpioneer.com In this video, we will look at several example trace files that demonstrate how TCP behavior can impact application performance. Rather than starting at the cable and working up to the application in the OSI model, we will learn how to start at the transport layer, reducing the amount of time it takes to solve the problem. We will also look at issues with TCP windows, TCP MSS, and how to interpret retransmissions and out-of-orders. Instructor: Chris Greer, Network Analyst, Packet Pioneer, LLC Chris is a Network Analyst for Packet Pioneer, a professional services and training company. He regularly assists companies in tracking down the source of pesky network and application performance problems using a variety of protocol analysis and monitoring tools including Wireshark.

How To Do Capacity Planning

Most IT organizations tend to manage system performance in a reactionary fashion, analyzing and correcting performance problems as users report them. When problems occur, hopefully system administrators have tools necessary to quickly analyze and remedy the situation. In a perfect world, administrators prepare in advance in order to avoid performance bottlenecks altogether, using capacity planning tools to predict in advance how servers should be configured to adequately handle future workloads. Watch as capacity planning expert Jon Hill explains the 3 crucial steps of successful capacity planning. Hill then performs real world demonstrations that detail each step using TeamQuest Performance Software. If you're in the capacity management arena or just want to know more on how to efficiently manage IT infrastructure performance; this video is a must see.

GTAC 2013: Web Performance Testing with WebDriver
 
14:25
http://g.co/gtac2013 Slides: http://goo.gl/5QHVY Demo code: https://gist.github.com/klepikov/5457750 Michael Klepikov, Google In web performance testing, we know pretty well how to analyze a page load. We need to move beyond a page load though: modern apps are highly interactive, and operations tend not to reload the entire page, but rather update it. Different people, myself included, have integrated WebDriver into web performance test harnesses, which helps, but still keeps performance tests separate from the rest of the UI test suite. I propose to build performance testing features right into WebDriver itself, leveraging its recently added Logging API. This makes it possible to collect performance metrics while running regular functional tests, allowing for a much more seamless integration of performance tests into the overall development and test flow. It is also much less disruptive to the custom build/test toolchains that almost every large organization creates. I will demonstrate this with the new-generation ChromeDriver (WebDriver for the Chromium browser).

Building and Tuning High Performance Java Platforms
 
01:32:07
Recorded at SpringOne2GX 2015 Speaker: Emad Benjamin, VMWare Slides: http://www.slideshare.net/SpringCentral/building-and-tuning-high-performance-java-platforms This session will cover various GC tuning techniques and how to best build platform engineered systems; in particular the focus will be on tuning large scale JVM deployments. It is true that half of the world's Java applications have 2.x more hardware provisioned than what they really need, and 90% of these applications miss their SLA. In this session we showcase why this is the case, and demonstrate sizing techniques on how to platform engineer such systems without the need for over-provisioning and hence meeting SLA in a more feasible way. Come to this session to learn about GC tuning recipe that can give you the best configuration for latency sensitive applications. While predominantly most enterprise class Java workloads can fit into a scaled-out set of JVM instances of less than 4GB JVM heap, there are workloads in the in memory database space that require fairly large JVMs. We will look at various Java platform scales, some holding a few large JVMs of 90GB heap space, while other platforms are of thousands of JVM instances of less than 4GB heap space on each. We will also take a close look at an example XYZCars.com where a microservices approach was designed and deployed, we will talk through how to more correctly deploy microservices without out causing fragmentation of scale, and hence without impeding performance. In this session we take a deep dive into the issues and the optimal tuning configurations for tuning large JVMs in the range of 4GB to 360GB, using the GC tuning recipes that were gained over the past 15 years of GC tuning engagements. You should be able to walk away with the ability to commence a decent GC tuning exercise on your own. The session summarizes the techniques and the necessary JVM options needed to accomplish these complex tuning tasks, in addition to various virtualization best practices when dealing with such large Java systems. Naturally when tuning large scale JVM platforms, the underlying hardware tuning cannot be ignored, hence the session will take detour from the traditional GC tuning talks out there and dive into how you optimally size a platform for enhanced memory and CPU consumption.

While Dynatrace automatically detects anomalies in our environment and while the AI automatically points us to the root cause it is important to find ad-hoc answers to the diagnostics questions listed above. In this session, we learn where to start your "Diagnostics Journey" within the Dynatrace Web Interface.
