Webpage HTTP performance

Yahoo developers have encapsulated much of their experience in optimizing web sites and serving web pages in a Firefox add-in. It is called YSlow, I've been having decent success in analyzing pages using it as of late. It is simple and effective, a great little tool. Not everything is easily achievable and depending on the content you are delivering it might not be reasonable. In the end, I've been able to use it and spend a short amount of time to identify a number of changes needed for more rapid delivery of HTTP content.

Download it, install it, try it ...


Keywords: website performance, analyzing website performance, analyzing http performance, http performance, speed up web page delivery

Gentoo Portage and downgrading to older packages

All in the day of the life of an open source system.

Often I find myself using the time machine to discover whether some new install is the problem or something it depends isn't responding as expected.

So you want something older than curl 7.16 out of the portage tree? Use the less than (<) symbol:

emerge -av "<net-misc/curl-7.16.0"
