High Scalability - High Scalability - Tumblr Architecture - 15 Billion Page Views a Month and Harder to Scale than Twitter

by night.kame & 1 other

Node.js wasn’t selected because it is easier to scale the team with a JVM base. Node.js isn’t developed enough to have standards and best practices, a large volume of well tested code. With Scala you can use all the Java code. There’s not a lot of knowledge of how to use it in a scalable way and they target 5ms response times, 4 9s HA, 40K requests per second and some at 400K requests per second. There’s a lot in the Java ecosystem they can leverage.

Perfection kills » Profiling CSS for fun and profit. Optimization notes.

by karlcow

Fortunately, just few days before, Opera folks came out with an experimental “style profiler” (followed by WebKit’s ticket+patch shortly after). The profiler was meant to reveal the performance of CSS selector matching, document reflow, repaint, and even document and css parsing times.

Performance Calendar » Why Inlining Everything Is NOT The Answer

by karlcow

A user’s cache can only hold less than a day’s worth of browsing data: An average user browses 88 pages/day, an average page weighs 930KB, and most desktop browsers cache no more than 75MB of data. For mobile, the ratio is even worse.

Opera Dragonfly - Style profiler preview

by karlcow

As a real world example of how big the impact can be on performance, I made a test with the full HTML5 specification downloaded locally and ran the profiler. I noticed few of the most expensive selectors had ":link" and ":visited". I changed these to instead be "a:link" or "a:visited" (in this case they were equivalent in terms of which elements matched). This trivial change makes the engine use a cache, and bought the selector matching time down from about 14 seconds to about 11 seconds.

Inside Pantheon: the Valhalla filesystem | Pantheon

by holyver
At Pantheon, when we look at challenges Drupal projects face, we don't only do what's worked well-enough in existing deployments. We ask ourselves how we can transcend some of the challenges entirely. How Drupal stores files is no exception. So, when we started building the next generation of Pantheon (now launched), we looked at our options -- and then built a solution entirely focused on the needs of Drupal developers.

Perf4J

by astrochoupe
Perf4J is a set of utilities for calculating and displaying performance statistics for Java code. For developers who are familiar with logging frameworks such as log4j or logback, an analogy helps to describe Perf4J: Perf4J is to System.currentTimeMillis() as log4j is to System.out.println()
