So, I did some test of my new Entroware Apollo and got some nice results. Running on GNOME 3, realtime kernel and nothing much more (not even by boosting CPUs) the system performances are already very good, although none of the stability definitions have been respected.
I recently purchased an Apollo 1000 from Entroware, a young British company specialized in Linux computers. I had it with Ubuntu 15.04, not really my favorite Linux distro, but I needed a working Linux environment quickly to replace my old Presario CQ61, that seemed close to death (still alive and well though…). Only in the last days I have been able to install Arch Linux and do some audio configuration. The results are quite promising!
