I spent more time working on SSDs that weren’t the X25-M than the Intel drive itself. The Intel drive just worked as it should, the rest of them didn’t.

Fascinating article on SSDs. Until now, I have been aware of SSDs but largely ignored them due to cost-per-gigabyte for this heavy-duty data user. They're starting to get interesting. I doubt my _next_ drive will be an SSD, but the one after that probably will be. Given these sequential read/write numbers, I do look forward to putting my Aperture library on an SSD.

Best article about SSD technology ever written.

Recently, I bought a new USB flash drive and wanted to know whether the specs matched up to what it can actually do. Usually these days most USB flash drives

The Browser Benchmark by Futuremark Corporation

Find out which is the fastest browser on your system with Peacekeeper, the browser benchmark from Futuremark. Peacekeeper measures browser speed with a wide range of JavaScript tests and displays the results in an easy to understand format.

Interesting graphs of languages lining up code size with speed. Use at your own risk.

a first step to investigate search engine.

Later this month we will be presenting a half day tutorial on Open Search at SIGIR. It’ll basically focus on how to use open source software and cloud services for building and quickly prototyping advanced search applications. Open Search isn’t just about building a Google-like search box on a free technology stack, but encouraging the community to extend and embrace search technology to improve the relevance of any application.

I just foolishly got caught in a You-Tube discussion on Java vs C performance. Foolish because You-Tube comments are a lousy way to present anything and because it's hard to keep the level of discourse scholarly. And foolish especially for me because I've had this discussion so many times and it always comes out the same way... so here's my attempt at distilling my arguments into something I can point people the *next* time I get caught in this silly discussion. Is Java faster than C/C++? The short answer is: it depends.

This tool lets you test web pages that are directly accessible as an URL from the Internet.

Welcome. Pagetest allows you to provide the URL of a webpage to be tested. The test will be conducted from the location specified and you will be provided a waterfall of your page load performance as well as a comparison against an optimization checklist. Please visit the PageTest wiki page for more information. Sample results for AOL.com can be seen here.

Namebench 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.

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. namebench runs on Mac OS X, Windows, and UNIX, and is available with a graphical user interface as well as a command-line interface.

A unique, comprehensive, accurate & free Windows (and Linux/Wine) utility to determine the exact performance of local and remote DNS nameservers . . .

This also shows that for massively concurrent problems, such as lots of parallel comet connections, the GIL in Python is a non-issue as we handle the concurrent connections in a single thread. In this post i am going to look at a selection of asynchronous servers implemented in Python.

AMD Phenom 9750 Quad-Core is the most bang for the buck, according to Paul's analysis (nice!)

Network latency and bandwidth are the two metrics most likely to be of interest when you benchmark a network. Even though most service and product advertising focuses on bandwidth, at times the latency can be a more important metric. Here's a look at three projects that include tools to test your network performance: nepim "network pipemeter," LMbench, and nuttcp.
