Redis Cluster is the native sharding implementation available within Redis that allows you to automatically distribute your data across multiple nodes without having to rely on external tools and utilities. At ScaleGrid, we recently added support for Redis Clusters on our platform through our fully managed Redis hosting plans. In this post, we’re going to introduce you to the advanced Redis Cluster sharding opportunities, discuss its advantages and limitations, when you should deploy, and

In software, compilers can often optimize away integer divisions, and replace them with cheaper instructions, especially when the divisor is a constant. I recently wrote about some work on faster remainders when the divisor is a constant. I reported that it can be fruitful to compute the remainder directly, instead of first computing the quotient (as compilers are doing when the divisor is a constant).

instant.page is a pretty cool project from Alexandre Dieulot. Alexandre has been at this idea for half a decade now, as InstantClick is his and is essentially the same exact idea. The idea is that there is a significant delay between hovering over a link and clicking that link. Say it takes you 300ms of delay. That 300ms could have been spent preloading the next page.

Although there are similarities between Push and Preload, they are two distinct features and each serve their own purpose. In this article, we’ll go over the similarities and differences between HTTP Preload vs HTTP/2 Push and discuss when it makes sense to use each.

Why do fast sites make more money? Because of nobody like a slow website. 14% of your audience will start shopping at another site if your page loads are slow, and 23% will simply stop the shopping experience or walk away from the computer. That has a huge affect on your business bottom line. Getting your websites, images, and videos to load quickly is an absolute necessity for inbound marketing success.

My Twitter profile currently includes the phrase “silence is violence.” People ask me about this occasionally: what does it mean? I don’t know where I picked up this phrase, and maybe it has a different meaning for me than for others, but what I mean by it is that if I’m a bystander who witnesses something I disagree with, I’m actively supporting the behavior to which I object.

While REST APIs are amongst the most popular when it comes to client consumption, they are not the only way to consume data and they aren’t always the best way. For example, having to deal with many endpoints or endpoints that return massive amounts of data that you don’t need are common. This is where GraphQL comes in. With GraphQL you can query your API in the same sense that you would query a database.

Loading scripts asynchronously is critical for getting pages to render more quickly. We care about rendering because that's what users see; if rendering is slow users have a negative experience. But it's not just about what users see - how the site feels is also important. That's why we focus so much on CPU time. If the CPU is blocked, then browsers are delayed responding to user interactions like scrolling and clicking on links.

I recently wrote about the growing fear produced by the mounting performance pressure of the Big Shift. As fear grows we have a natural human reaction to hold onto what we have. While very understandable, that reaction can also be very dangerous and lead us to miss the expanding opportunities created by the Big Shift. The two most prominent images – walls and safety nets - dominating much of our conversation these days are manifestations of our fear and desire to hold onto what we have.
