Most tools for measuring web performance come in two flavors: Developer-installed tools (Firebug, Fiddler, etc.) that allow individuals to closely trace single sessions or third-party performance monitoring systems (Gomez, Keynote, etc.) that will hit your site occasionally and report back component-level metrics (for a fee). Neither of these tools give you real-world information on what’s actually happening with your clients—how long are pages really taking to load, what’s the real cost of client-side execution, and what’s the impact of your loading or dependency chain. This talk will provide more information on the problem and the current solutions, and why we rolled our own, provide a technical overview of Jiffy, and show some real-world lessons we’ve had using it in our own production environment.

If you're just itching for an excuse to reuse that retired desktop PC or laptop sitting in your closet there here's your chance. Today we'll be looking at the basics of installing FreeNAS, an open-source DIY NAS. So instead of spending money on off the shelf options why not save yourself some cash and make use of the stuff you already have and get a super customizable network storage device to boot.

All you need to build your own is a copy of the FreeNAS installer, and a PC. It doesn't take much of a PC: just 96MB of RAM a NIC, and a CD-ROM to install from along with a hard drive, and you're ready to go. Tho you'll probably want at least one fat new hard drive to stash your stuff on!

FYI: FreeNAS isn't the only option if you're intent on rolling your own NAS. Other options include Openfiler a great alternative to FreeNAS.
