But most of the linux kernel hackers run Fedora (Linus) or work for Redhat (Dave). Linux specifically uses Fedora because it just works. I'm also not sure what you mean by faster? There's a lot of factors in play in terms of OS efficiency and benchmarking is hard. Like I said, I do think that Ubuntu dominates small business, but large businesses still focus on RHEL. Cloud has just made numbers like number of installs easier to track. I wouldn't necessarily say that number of installs really even matters compared to what those installs are being used for, and how much clout Canonical has in the Linux community versus Redhat. Redhat directly employees a ton of critical people in standard Linux projects like freedesktop etc.
