Since 2006, antiX has been one of my favorite distributions. There are several reasons for this. 1. I have, for many years, preferred to use Debian based software on my favorite systems. The antiX distribution is based on Debian Testing repositories and MEPIS installation and configuration tools. 2. I like flexible, configurable systems. The antiX configuration tools are among the very best available. 3. I like the MEPIS project, and when the antiX project emerged, I found I liked antiX as well, maybe even better, than the main MEPIS project, which I also like quite a bit.
I used antiX a bit once I installed the new version and now I am using it a bit more today. I did find one thing that represents somewhat of an issue: the default Web browser, Iceape, is prone to oscillate, using high percentages of CPU time, then back off, returning to normal.
Running my own instance of Firefox in my own directory, it has some CPU bursts as well, but they are not as prominent, and do not seem to affect the user interface - such as typing in a Web based text widget, such as this one, as much as with the default Iceape.
I will do some more experimenting, installing my own versions of browsers and see how they behave here. The only things chewing up CPU and memory here are the browsers, so it could be that the version of Iceape in Debian Testing is a bit suspect. More research will tell.
That's a nit for me; I run lots of stuff anyway, and with the great flexibility inherent in antiX, I have no problem at all getting what I want and configuring it the way that I want.
