Performance Budget Metrics

The Persistent Imbalance Between Supply and Demand for Software Development Labor

The Agile Manager

The growth in demand for software has consistently outpaced the growth in the supply of software developers. This has been the case for well over half a century. It's worth looking at why. Each major expansion in software development - automation (60s), productivity (80s), internet (90s), mobile (00s) - has been additive to the total stock of software in the world.

Frames Per Second Prefab

Memory Bandwidth Requirements of the HPL benchmark

John McCalpin

The High Performance LINPACK (HPL) benchmark is well known for delivering a high fraction of peak floating-point performance. The (historically) excellent scaling of performance as the number of processors is increased and as the frequency is increased suggests that memory bandwidth has not been a performance limiter. But this does not mean that memory bandwidth will *never* be a performance limiter.

Reducing JavaScript Bloat with Shoestring

Tim Kadlec

Those smart and clever folks at The Filament Group formally announced yet another useful tool yesterday: a “lightweight, simple DOM utility” they call Shoestring. I’ve been using Shoestring for awhile now, and I’m a huge fan. In fact it has become my go-to solution when I need such a tool. It’s small, powerful, and very, very smart. It’s very rare that I write about a specific tool. Tools come and go.

"RWD is bad for performance" is good for performance

Tim Kadlec

Myths are powerful things. They certainly have the ability to destroy—we’ve seen that many times. But put the right spin on a myth and you can use it to build up; to create something new and better. Responsive design just can’t seem to shake the rumor that it’s bad for performance. It’s very frequently spouted as a downside of the technique—a reason why you may not want to pursue responsive design for a project. Just to be clear where I stand on this: I don’t agree.

Why RWD looks like RWD

Tim Kadlec

This morning, Mark Boulton wondered aloud on Twitter about why responsive design “looks” like responsive design: I wonder if #RWD looks the way it does because so many projects aren’t being run by designers, but by front-end dev teams. This certainly isn’t the first time that someone has suggested that responsive sites have a “look” to them. In fact, it seems that particular topic has been quite popular over the last few years.

Beyond Responsive

Tim Kadlec

Jason Grigsby just wrote an excellent post talking about how he’s wrestled with trying to define “responsiveness”. When a client comes to us to help them make their existing site or app responsive, we know that we’re going to be using fluid grids, flexible images and media queries. But we also know we’re going to be using much more than just those three techniques. The best responsive web designs are doing much more.

Performance Budgeting with Grunt

Tim Kadlec

It seems like the idea of performance budgeting has been gaining quite a bit of traction over the past year. This is awesome! The best way to improve web performance is to prioritize it from the get-go, and that’s exactly what a performance budget helps you do. But having the budget set in a document somewhere doesn’t accomplish much. It needs to be enforced to really matter. I’m a big fan of Grunt.js and use it on pretty much every project at this point.

Book Review: Responsible Responsive Design

Tim Kadlec

Yesterday Guy Podjarny published his analysis of the use of responsive design among the top 10,000 websites. He found that adoption jumped from 10.8% to 18.7% over the last year. Another recent survey showed that a hefty 90% of publishers are looking at implementing responsive design. However you want to slice it, responsive design is an increasingly popular technique. But there are tricky issues to navigate along the way: tables, performance, and input modes—oh my!

The Story of Apollo - Amazon’s Deployment Engine

All Things Distributed

Automated deployments are the backbone of a strong DevOps environment. Without efficient, reliable, and repeatable software updates, engineers need to redirect their focus from developing new features to managing and debugging their deployments. Amazon first faced this challenge many years ago. When making the move to a service-oriented architecture, Amazon refactored its software into small independent services and restructured its organization into small autonomous teams.

The Easiest Way to Compute in the Cloud – AWS Lambda

All Things Distributed

When AWS launched, it changed how developers thought about IT services: What used to take weeks or months of purchasing and provisioning turned into minutes with Amazon EC2. Capital-intensive storage solutions became as simple as PUTting and GETting objects in Amazon S3. At AWS we innovate by listening to and learning from our customers, and one of the things we hear from them is that they want it to be even simpler to run code in the cloud and to connect services together easily.

Deflation and Technical Debt

The Agile Manager

Technical debt is a useful metaphor for explaining why some code is faster to complete but more expensive to maintain. It is also helpful in explaining design decisions made for sake of expediency, or because of an outright lack of knowledge. Tech debt can be a real burden on development, particularly as it takes away time that would otherwise be directed toward productive investment in new feature development.

Knowledge Versus Wage Work in Software Development

Page weights and load times vary so much from site to site and industry to industry.

Notes on: 'Performance Culture' at Google I/O 2014

At Google I/O 2014 , Lara Swanson and Paul Lewis discussed performance culture. Since it’s one of my favorite topics, I decided to share my notes: 34% of US adults use a smartphone as their primary means of internet access. Mobile networks add a tremendous amount of latency. We are not our end users. The new devices and fast networks we use are not necessarily what our users are using. 40% of people abandon a site that takes longer than 2-3 seconds to load.

Fast Enough

Tim Kadlec

How fast is fast enough? I’m asked this question a lot. Page weights and load times vary so much from site to site and industry to industry. While it’s easy to spot the obviously bad examples, it can be much more difficult to find the line between is “fast enough” and what is slow. My usual answer of “make it as fast as possible” doesn’t seem to make people very happy, so let’s try to get at least a little more concrete. Compare.
