YSlow, the performance lint tool created by the Yahoo! Exceptional Performance team was updated to version 0.9.3. today. This minor version increment contains:
- Firefox 3 support (up to and including 3.0b4pre)
- Sortable table of page components in the Components tab
- Beacons (1x1 images that are not part of the DOM) excluded from the overall score. If you want them back in the score, use
about:configto set the option
- Minor bug fixes that caused YSlow to freeze as it peels off the page components (encountering streams, applets, empty URLs)
In the spirit of openness and our commitment to a faster experience on the web, we hope you join us in accelerating the user experience.
You can download the tool here, report bugs here, read the performance rules, and participate in the performance mailing list discussions. Also make sure you keep an eye on our performance-related postings on YDN and YUI Blog.
