The paper MegaPipe: A New Programming Interface for Scalable Network I/O (video, slides) hits the common theme that if you want to go faster you need a better car design, not just a better driver. So that's why the authors started with a clean-slate and designed a

"It’s all a numbers game – the dirty little secret of scalable systems" Martin Thompson is a High Performance Computing Specialist with a real mission to teach programmers how to understand the innards of modern computing systems. He has many talks and classes (listed below) on caches, buffers,

When you have a large population of servers you have both the opportunity and the incentive to perform interesting studies. Authors from Google and the University of California in Optimizing Google’s Warehouse Scale Computers: The NUMA Experience conducted such a study, taking a look at how jobs run on

What data structure is more sacred than the link list? If we get rid of it what silly interview questions would we use instead? But not using linked-lists is exactly what Aater Suleman recommends in Should you ever use Linked-Lists? In The Secret To 10 Million Concurrent Connections one of
Example
Now that we have the C10K concurrent connection problem licked, how do we level up and support 10 million concurrent connections? Impossible you say. Nope, systems right now are delivering 10 million concurrent connections using techniques that are as radical as they may be unfamiliar. To learn how it’s

Performance guru Steve Souders gave his keynote presentation, Cache is King! (slides), at the HTML5DevCon, besides being an extremely clear explanation of how caching works on the Internet and how to optimize your use of HTTP to get the best performance, Steve ran experiments that found some surprising results on

Debugging complex problems is 90% persistence and 50% cool tools. Brendan Gregg in 10 Performance Wins tells a fascinating story of how a team at Joyent solved some weird and challenging performance issues deep in the OS. It took lots of effort, DTrace, Flame Graphs, USE Method, and writing custom

Recently, I was working on a project that was coming to a close. It was related to optimizing a database using a Java based in-memory cache to reduce the load. The application had to process up to a million objects per day and was characterized by its heavy use of
Scalability
Distributed systems are not typically a place domain driven design is applied. Distributed processing projects often start with an overall architecture vision and the idea about a processing model which basically drives the whole thing, including object design if it exists at all. Elaborate object designs are thought of as

Performance is critical to the success of any web site, and yet today's web applications push browsers to their limits with increasing amounts of rich content and heavy use of Ajax. In his new book Even Faster Web Sites: Performance Best Practices for Web Developers , Steve Souders, web

(Please bare with me, I'm a new, passionate, confident and terrified programmer :D ) Background: I'm pre-launch and 1 year into the development of my application. My target is to be able to eventually handle millions of registered users with 5-10% of them concurrent. Up to this
