Javascript Library Performance Test Roundup

This is a test system built by members of the PBwiki engineering team in order to gather data about browser and javascript library performance. All results are published live on the summary page for public consumption. Thanks for helping us make the internet a little faster!

The following test will time how long it takes to load the following libraries:

• Dojo (1.0.1)
• jQuery (1.2.1)
• Prototype (1.6.0)
• YUI (utilities bundle) (2.4.0)
• Protoculous (1.0.2) (prototype-1.5.1 + scriptaculous-1.7.1)

Test variants:

• Toolkit packaging
  • Raw - raw JS source
  • Minimized - run through the YUI compressor
  • Packed - "factory" packed version, usually one large eval() that uncompresses the script
• Normal vs. Gzipped
• Normal vs. Cached
• 1232 browsers/OS combos (so far)
• Server location: US-East, US-West
