Web Analytics for Beginners - Presented by Bluehost
 
04:35
[http://blue.host/EwsZ303GsQd] Tracking four basic metrics (total traffic, source of traffic, bounce rate, and conversion rate) can help small business owners fine-tune their web strategy and, ultimately, increase profits. There are countless things on your website that you can measure and analyze, but in this video, we focus on four key metrics for beginners. Total Traffic — The number of people visiting your site is a strong indicator of its overall health. This measurement can also help you identify what you’re doing right. For example, if you get a huge spike in traffic after publishing a guest post, you know your visitors liked the content. Source of Traffic — This measurement tells you how people are finding your website online. This can help you create a strategy going forward. If you find that most of your new visitors come for your social media posts, you’ll know that you should direct your efforts at creating more social content. Bounce Rate — A bounce is when a visitor leaves your site before clicking on another page. A high bounce rate can mean that the people coming to your site aren’t sticking around to make a purchase. This could be for a variety of reasons, including unappealing content, unattractive website design, or a hard-to-navigate menu. Conversion Rate — Conversion rate is the percentage of visitors who actually do what you’re asking them to do on your site, such as buy your product or subscribe to your blog. The higher your conversion rate, the better your site is doing. A low conversion rate can signal that your content and call to action are weak. Tracking web analytics does require time and effort, but carefully deciphering the data can lead to a more effective website — and more sales.

Use Chrome Developer Tools to Test Website Speed & Performance at Different Internet Connections
 
05:53
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.

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.

Slides: http://www.slideshare.net/brendangregg/velocity-2015-linux-perf-tools or http://velocityconf.com/devops-web-performance-2015/public/schedule/detail/42513 Description: " There are many performance tools nowadays for Linux, but how do they all fit together, and when do we use them? This tutorial explains methodologies for using these tools, and provides a tour of four tool types: observability, benchmarking, tuning, and static tuning. Many tools will be discussed, including top, iostat, tcpdump, sar, perf_events, ftrace, SystemTap, sysdig, and others, as well observability frameworks in the Linux kernel: PMCs, tracepoints, kprobes, and uprobes. This tutorial is updated and extended on an earlier talk that summarizes the Linux performance tool landscape. The value of this tutorial is not just learning that these tools exist and what they do, but hearing when and how they are used by a performance engineer to solve real world problems — important context that is typically not included in the standard documentation."

O'Reilly Webcast: How to Boost Web Performance Using API Monitoring
 
01:07:29
Maybe your approach to web application monitoring is out of balance. Often the focus is on synthetics, log monitoring, and even browser instrumentation -- which is enough for end user monitoring but often misses an important angle -- APIs. Just not enough attention is given to API, REST and SOAP -- especially as companies expand web application partner channels and mobile applications. In this live 45 min. webcast, join Dell product expert John Spirko, Dell software engineer manager Rob Dickinson and Dell software development senior consultant Andy Wahrenberger in an exclusive webcast with O'Reilly. John discusses the attributes of a SOAP request/response pair, why URL identification isn't enough to pinpoint SOAP API issues and the two main perspectives to consider for SOAP API monitoring.

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).

Performance Testing Interview Questions
 
07:05
________ ONLINE COURSES TO LEARN ________ https://automationstepbystep.com/909-2/online-courses/ Performance Testing Interview Questions JMeter Interview Questions Hi Raghav. Have one query. Today I have given one interview for performance with Jmeter. The interviewer asked me how we will do end to end performance testing. ? How to convince a client that performance testing is necessary for you. How to test with 1000 user, what all approaches to follow? Can you give me answers to all these Please help Thanks Utkarsh _________________________________________________ How we will do end to end performance testing? First thing will be to clarify on what is meant by end-to-end performance testing and what is in scope. So first you will create a plan as per the in-scope items. Scope | Expected Load | Geographical distribution | You will need a separate env for performance testing. Will analyze and take up the modules/scenarios where performance needs to be checked most. While setting up performance test you will need information on: min, max, avg load expectations. geographical distribution You can start with Network API calls test and can go to UI level. How to convince the client that performance testing is necessary for you? Here if you can provide some specific and generic examples, that will help you. Usually, in an organization, examples are given of past projects where performance testing helped to make the application efficient and helped to avoid performance issues in production. You can also give some ROI calculation like with Automated performance testing you can create 1000's of virtual users and can test the impact without creating a costly infrastructure. How to test with 1000 user, what all approaches to follow? We never start directly with max user load. First, create a sample test plan and test it with single or max 10 users. Get it approved and then increase the count gradually. Also ensure this test is performed on a separate environment, so not to compromise on any existing env in use by other teams. After this, you should run your tests for 100 users, 200, 500, 700, 1000 etc. This no can vary based on application performance and infrastructure. You should also get some SLA for comparison of your results. Else you need to create a baseline first and then compare your subsequent results with this baseline. Suppose you get a huge time with 100 users on some request which is not expected, then you can share the results and ask if you should proceed with more users or wait until the issue is fixed. So overall, Utkarsh, you have to show your experience and observation skills here. No one is expecting a perfect answer (most of the cases the other person also does not know it). You should know what you speak as there can be a counter question. With experience, you will know it all.
