I have an old Xserver running El Capitan and was gonna throw O3x on it to use on my network, but was wondering how performance compares to say FreeBSD and if it would be worth it to just reinstall the OS.
Also, I can't upgrade past El Capitan. I know 2.2.3 runs fine on Cap but I saw 2.3.0 release candidate only supports the latest two releases of OS X. Is that just because of its RC status or have older versions been dropped?
