Is Your Computer Stable?
Everyone breathes a sigh of relief when their newly built computer boots up for the first time, no matter how many times they've done it before. But booting is only the beginning of the story. Yeah, it boots, great. Color me unimpressed. What we really need to know is whether that computer is stable.

Although commodity computer parts are more reliable every year, and vendors test their parts plenty before they ship them, there's no guarantee all those parts will work reliably together, in your particular environment, under your particular workload. And there's always the possibility, however slim, of getting very, very unlucky with subtly broken components.

Because we're rational scientists, we test stuff in our native environment, and collect data to prove our computer is stable. Right? So after we boot, we test.

JoeBlog Siege Home
Siege is an http load testing and benchmarking utility. It was designed to let web developers measure their code under duress, to see how it will stand up to load on the internet. Siege supports basic authentication, cookies, HTTP and HTTPS protocols. It lets its user hit a web server with a configurable number of simulated web browsers. Those browsers place the server “under siege.

Benchmarking Redis on AWS ElastiCache — Meldium
Amazon announced last week that the AWS ElastiCache service now supports the Redis protocol. We decided to benchmark all the available instance types to see what gives both the best raw performance, and the best bang for the buck. For most users, the m1-medium, m1-large, and especially m2-xlarge instances are the best combination of price, performance, and available memory.

byte-unixbench - Project Hosting on Google Code
UnixBench is the original BYTE UNIX benchmark suite, updated and revised by many people over the years. The purpose of UnixBench is to provide a basic indicator of the performance of a Unix-like system; hence, multiple tests are used to test various aspects of the system's performance. These test results are then compared to the scores from a baseline system to produce an index value, which is generally easier to handle than the raw scores. The entire set of index values is then combined to make an overall index for the system.

namebench - Project Hosting on Google Code
Are you a power-user with 5 minutes to spare? Do you want a faster internet experience? Try out namebench. It hunts down the fastest DNS servers available for your computer to use. namebench runs a fair and thorough benchmark using your web browser history, tcpdump output, or standardized datasets in order to provide an individualized recommendation. namebench is completely free and does not modify your system in any way. This project began as a 20% project at Google.

Journal of Eivind Uggedal: VPS Performance Comparison
My latest side project, was it up?—a free web monitoring service, required a number of VPS instances due to its distributed nature. I previously conducted a comparison of Slicehost and Prgmr. This time I needed to purchase several instances and therefore went out and did a more throughout and wider comparison of which VPS provider would give me the most bang for my buck. I targeted VPS offerings in the $20 space (and the cheapest Amazon EC2 option). Summarizing the benchmarks gives us one clear winner: Linode.

Tokyo Cabinet vs Memcached
Tokyo Cabinet bills itself as a next-generation DBM. Like BerkeleyDB, TC gives you low-level database operations and allows you to build your own very fast data access operations. Unlike BDB, TC has several functional layers on top of TC which provide network access, schema-less document-oriented storage (a la CouchDB) and supported bindings for many languages. This project is an infrastructure nerd’s dream!

James on Software | Introducing Trample: A Better Load Simulator
Most load sim tools make requests to a static list of urls. Unfortunately, this kind of load simulation is unrealistic. Trample is a more flexible load simulator. Instead of a static list of urls, trample's configuration language is ruby. Using ruby's blocks (lambda functions), it's possible to randomize the requests that get made in each thread, as well as the user that logs in.

Nimble Method: The future of Rails is Ruby 1.9 - real performance of 1.8, JRuby and 1.9 compared
We ported Acunote - our online enterprise project management and Scrum software to both JRuby and Ruby 1.9 and ran our set of performance benchmarks. Ruby 1.9 is 2x faster than 1.8. But the real world improvements are even better.
