Yeah, the number of BSD CVEs just boils down to the fact that nobody cares about BSD. Since nobody cares about it, its performance is also very 20-years-ago and doesn't stand up to modern linux performance. You could expect database performance (e.g. postgresql) to be 2-4x higher on linux under a highly concurrent load. There are thousands of full-time professionals around the world focused on linux performance and the applications are co-evolving to work best on linux so you can't expect cutting-edge speed from freebsd.
There's probably a niche for freebsd but unless you know exactly what it is and how to exploit that niche, you're not going to find it by accident.
