# Web Performance: Some posts of interest

This morning's bounty of posts brought in two that will make you think.

First was [Port80 Software's comments](http://www.port80software.com/200ok/archive/2006/07/31/2318.aspx) on using the Cache-Control mechanism embedded in all browsers. This is interesting to read, as I have been trying to get companies to use this mechanism more intelligently for a number of years. I know that the Port80 team gets it, but it is always nice to have some outside validation of a position you have tried to evangelize for a long time.

The second was [Tim O'Reilly's post](http://radar.oreilly.com/archives/2006/07/creating_scalable_websites.html)on [Cal Henderson's](http://www.plasticbag.org/archives/2005/06/cal_henderson_on_how_we_built_flickr.shtml) new book on Web scalability. While I am likely to purchase the book for a professional interest, I have one problem with Flickr's current configuration: *static.flickr.com* does not use HTTP persistence, something [I noted last week](http://crazycanuck.org/index.php/2006/07/21/web-performance-flickr-do-you-want-to-get-faster/). This strikes me as weird.

It's always good to see Web performance rear its head.
