An important rule when building a highly available and highly reliable system is to design for failure. In other words, your design model should assume that, as Amazon CTO Werner Vogels has said, “everything fails all the time.” Fortunately, modern data centers, networks, and servers are highly reliable, and failures…
Hello everyone! I'm very pleased to announce that we've just managed to merge the optresult branch. Under this cryptic name is the bigges...
Create an infrastructure for parallel computation in PostgreSQL. This does four basic things. First, it provides convenience routines to coordinate …
We’ve been doing a bunch of work recently on improving the responsiveness of OCaml’s garbage collector. I thought it would be worth discussing these developm...
Customers ask us for p99 (99th percentile) of metrics pretty frequently. We plan to add such a feature to Database Performance Monitor (DPM)(more on that later). But a lot of the time, when customers make this request, they have something very specific, and different, ...
MariaDB 10.1 not only contains tons of new features, it has also been polished to deliver top performance. The biggest improvement has been achieved for scalability on massively multithreaded hardware. The following numbers show the throughput for a simplified sysbench OLTP benchmark on MariaDB-10.1.8 compared to…
Recently I’ve been deliberately working on some areas of Firefox I’m unfamiliar with, particular relating to graphics. This led me to rewriting Firefox’s BMP decoder and learn a number of interesting things along the way.
One of the headline features of CockroachDB is its full support for ACID transactions across a distributed database. In this post, we’ll explain...
Not just another Hadoop rant — I promise
Its been a while since I mentioned Wayland in this space - of course that doesn't mean that work on GNOME Wayland support has stopped. Quite the opposite, in fact. The GNOME 3.15.4 release that is due this week will close a number of the remaining gaps: libinput 0.8 has been released, with most of...
In a previous post we discussed the performance limitations of the Linux kernel network stack. We detailed the available kernel bypass techniques allowing user space programs to receive packets with high throughput.
Building the platform where people around the world come to search, save and shop
As you may know, Visual Studio now supports building Android and iOS applications using Clang. We realize the need of our users to write cross-platform
asm.js is an easy-to-optimize subset of JavaScript. It runs in all browsers without plugins, and is a good target for porting C/C++ codebases such as game engines - which have ...
In a recent blog post we explained how to tweak a simple UDP application to maximize throughput. This time we are going to optimize our UDP application for latency. Fighting with latency is a great excuse to discuss modern features of multiqueue NICs.
League of Legends players collectively send millions of messages every day. They're asking friends to duo-queue, suggesting a team comp on the champ select screen, and thanking opponents for a good game. On July 21st of this year (I p…

MIT researchers have developed the first fundamentally new approach to cache coherence in more than three decades. The more-efficient memory-management scheme — nicknamed Tardis for its time-saving properties — could help enable chips with thousands of cores.
The upcoming 2.1 release will introduce important improvements , including support for automatic failover. Although we’re still hard at work on the finishing touches that will make the new features ready for production use, the beta offers an opportunity to get an early look.
