Seriesly - Document Oriented Time Series DB
So, I started writing a document-oriented time-series database in go two weeks ago. It’s really nothing groundbreaking, but it’s been quite fun. My purpose is to have a system that allows me to store arbitrary performance data captured as it’s seen in the wild, and then later come up with ways to look at it. Check out this real life example to get a feel for the kinds of captures we’re working wit

Which Java thread consumes my CPU?
What do you do when your Java application consumes 100% of the CPU? Turns out you can easily find the problematic thread(s) using built-in UNIX and JDK tools. No profilers or agents required. For the purpose of testing we'll use this simple program: [code language="java"] public class Main { public static void main(String[] args) { new Thread(new Idle(), "Idle").start(); new Thread(new B

Cache them if you can | High Performance Web Sites
March 22, 2012 10:41 pm | 24 Comments “The fastest HTTP request is the one not made.†I always smile when I hear a web performance speaker say this.

I’ve written extensively about caching: Call to improve browser caching (lack
Don’t docwrite scripts | High Performance Web Sites
April 10, 2012 5:29 pm | 32 Comments In yesterday’s blog post, Making the HTTP Archive faster, one of the biggest speedups came from not using a script loader. It turns out that script loader was using document.write to load scripts dynamically. I wrote about the document.write technique in Loading Script Without Blocking back in April 2009, as well as in Even Faster Web Sites (chapter 4). It look
Clearing Browser Data | High Performance Web Sites
September 10, 2012 7:50 pm | 13 Comments In Keys to a Fast Web App I listed caching as a big performance win. I’m going to focus on caching for the next few months. The first step is a study I launched a few days ago called the Clear Browser Experiment. Before trying to measure the frequency and benefits of caching, I wanted to start by gauging what happens when users clear their cache. In additio
