OSCON 2006: Ajax Optimization Techniques
This week, Kevin Yank is reporting from OSCON 2006 in Portland, OR.
- JSmin — aggressive, but doesn’t modify names
- ShrinkSafe — less aggressive (more readable output), but reduces variable names
- mod_gzip, mod_deflate — Apache modules that will compress web content before sending it to a browser that supports decompressing it
His second case study was lala.com, the HTTP caching of which is immaculate, but the site requires the browser to download so many files that load time is slowed down significantly by the limit on the number of simultaneous requests. This is readily apparent when viewing the request timeline for the site using a tool like Tamper Data.
