Cuzillion
At Web 2.0 Expo today I announce the release of Cuzillion. The tag line is ‘cuz there are zillion pages to check. It’s indispensable for people like me who are always pushing browsers to their limit trying to figure out how to squeeze out a little more performance.
I’m constantly thinking of or being asked about how browsers handle different sets of resources loaded in various ways. Before I would open an editor and build some test pages. Firing up a packet sniffer I would load these pages in different browsers to diagnose what was going on. I was starting my research on advanced techniques for loading scripts without blocking and realized the number of test pages needed to cover all the permutations was in the hundreds. That was the birth of Cuzillion. (more…)
Roundup on Parallel Connections
A lot of blogging and follow-up discussion ensued with the announcement that IE8 supports six connections per host. The blogs I saw:
- IE8: The Performance Implications
- IE8 speeds things up
- IE8: 6 Connections Per Host
- IE 8 and Performance
- Testing IE8.s Connection Parallelism
- IE 8 Connection Parallelism Issues
It’s likely that Firefox 3 will support 6 connections per server in an upcoming beta release, which means more discussion is expected. I wanted to pull all the facts into one place and make several points that I think are important and interesting. Specifically I talk about:
- the HTTP/1.1 RFC
- settings for current browsers
- upperbound of open connections (cool!)
- effect of proxies
- will this break the Internet?
