On the Season 2 debut of Lost Cultures: Living Legacies , we travel to Bermuda, an Atlantic island whose history spans centuries and continents. Once uninhabited, Bermuda became a vital stop in transatlantic trade, a maritime stronghold, and a cultural crossroads shaped by African, European, Caribbean, and Native American influences. Guests Dr. Kristy Warren and Dr. Edward Harris trace its transformation from an uninhabited island to a strategic outpost shaped by shipwrecks, colonization, the transatlantic slave trade, and the rise and fall of empires. Plus, former Director of Tourism Gary Phillips shares the story of the Gombey tradition, a vibrant performance art rooted in resistance, migration, and cultural fusion. Together, they reveal how Bermuda’s layered past continues to shape its people, culture, and identity today. Learn more about your ad choices. Visit podcastchoices.com/adchoices…

But how can you test for those conditions beyond the capacity of your test lab environment? You gotta estimate future performance based on the results you gather in the lab.

Needle. Haystack. Go! Sometimes all we get from our load testing tools is a capture of the response times and throughput, and maybe some minimal resource monitoring if you're lucky. That means to actually see deeply into the application code as it is running, a diagnostics package can open that black-box to you, to find out exactly WHY the system is running slow. As you dig into the system under test you’ll be able to see exactly why the % CPU utilization is so high, and why so many bytes/sec are being pumped through the stack and exactly the SQL statements used by the database. In this Part 1 episode with our guest host and fellow performance guru Petar Puskarich, we'll chat about how to get started with diagnostics, handling politics and objectives, working with third party instrumentation and how Petar's first experiences back in 2001 aren't that unfamiliar to folks today.

Automate. Rinse. Repeat.

So, why not have performance testing be part of that continuous world? It’s a hot topic in this edition of PerfBytes where we are joined by our fellow pancake-loving co-originator Carlos Chidiac as we debate the value and pragmatics of integrating performance into your continuous integration and continuous delivery process automation. Don’t be scared by James’ Perf Rant about CPT, Agile & DevOps and Carlos who both agree that ‘Speed Kills’ when it comes to your attempts to accelerate performance through automation.

In this episode we’ll talk about the pitfalls of such behavior, the legitimate and not-so-legitimate arguments of tool blasphemers and also what you can do as a test manager to resolve such situations.

Here's a suggestion: flip up that blast shield and tell old Obi Wan Kenobi to take a try at scripting up a headless driver to generate transport-layer traffic with data correlation, randomization and parameters that simulates thousands or even millions of calls against the system. It's not so easy even when you use the force, eh old man!? In this first of two episodes Tim Koopmans will be joining us as we cover many of the virtual user scripting tips and tricks that we've learned over the many years of using almost every tool on the planet. Starting with the creation of a usage model, scripting practices, commonly used functions and all sorts of great ideas to help you get the scripting perfect and maintainable.

It's the Frackin' Load Balancer 1:09:32

Back when I grew up in Minnesota we played a game called "Duck, Duck, Gray Duck where one my friends would run around the circle of all us kids and tap us on the head - around and around. It's basically the same way a load balancing algorithm works to enable horizontal scalability of large systems. Except that the load balancer would not randomly tap one of us and say Gray Duck and then go sprinting around to take our spot. That's not actually how node eviction works in clustering. In this episode of PerfBytes we are joined by our old friend Alon Girmonsky from Blazemeter to discuss the common challenges with modern load balancers; both software and hardware types. Dan Bartow gives a rant about the past 7 years of bad load balancer performance. And James introduces a whole new type of pre-outage performance outage on News of the Damned.

It's a lonely life, as a performance tester in an agile shop. Your work is pushed to the end of the iteration and then they shut you in the lab for four days right before the release. Well, it's time to get performance up-and-out of the lab and build it into the sprint. That's right - you can become a fully-integrated part of the SCRUM as a performance engineer, enhancing each user story with your brilliance about performance. This epsiode of PerfBytes will help you to transcend the lowly life in the lab and engage up-front with developers, product owners and stakeholders to raise their attention to the ever-increasing importance of performance. Where a user story fails to include performance criteria, you'll be there. When a developer fails to run multiple threads of a unit test, you'll be there. Able to construct an integrated performance test into a single nightly test run, it's you to the rescue! We can't promise that they'll give you a promotion, but you might start wearing a home-made super-hero costume with a capital 'P' enblazed across your chest.…

Whether your an external contractor testing over the internet or an internal testing team with no other place to test, sometimes you have no choice but to do your performance testing in production. In this episode of PerfBytes, James and I will give you some tips about how to conduct performance tests in production safely.

Even major vendors like IBM and HP are behind the support for this nearly-enterprise-ready stack. Well, it would be totally enterprise ready if you can get it to scale and perform reliably enough to operate mission-critical applications. Join James and I for a sharing of our experiences tuning up LAMPs and illuminating the practices you'll need to succeed. Not that performance tuning wasn't already hard enough to do without proper lighting. Originally posted on Tuesday, February 19th, 2013.

It is not safe to drive a car with your eyes closed. It is also not safe to operate expensive, mission-critical computing systems without monitoring the performance. How much CPU did that query use? How much memory is being allocated/de-allocated? How many bytes per second are being sent and received from the browser? Monitoring the resource utilization of your application is an absolutely essential part of making the necessary calculations to properly test performance. Without those measurements, all you can do is take a guess? Client response time is only one part of the puzzle.

Web Performance Optimization 59:33

We tuned the databases - for scaling up and scaling out - grids and clouds and no-sql. We tuned the servers - for scaling up and scaling out - farms and clusters and automated deployment. We tuned the network - accelerations and caching and CDNs. What's next? Web Performance Optimization - appealing to developers and designers alike, we are focusing on that last (or maybe first) piece of the puzzle: the client-side. There's been an explosion of tools and techniques around browser optimization and performance analysis, since the first time Steve Souders released the first version of YSlow! Now we have a twitter hash tage #WPO, meetup groups from New York to Seattle, to Frankfurt and Beijing. Vendors are rampantly adding "web performance" capabilities in their existing tools - trying to catch-up with the myriad open-source utilities employed by engineers learning the #WPO craft.

Look, just because the Matrix was a complete virtual reality (complete with guns and motorcycles and the girl in the red dress), the virtualization fad in our REAL reality isn't quite so sexy. Beneath any gigantic array of virtualized hosts or zones, there are still physical machines and infrastructure supporting your application's performance. Even though I think it's been 5 years since I actually was forced to lay hands physically on a piece of hardware, most of us performance testers are still expected to be just as effective testing on these abstracted virtual systems. In this show the PerfBytes guys will review the challenges, pitfalls and good practices to conduct your load testing with shared resources and consolidated data sources.

You sent your top ten list of SQL queries to the DBA's - hopefully they got the changes committed in time. And now hopefully you have time to call in to PerfBytes and tell us all about it!! We'd love to hear from you folks who have been actively engaged in preparation for what is sure to be the worst day in Internet history.
