Earlier quoted context omitted.
There is a lot of functionality in Base that some aren't aware of: ldapd, httpd, IPSec + iked (VPN), pf (firewall, NAT), dhcpd, ntpd, smtpd, snmpd, radiusd, relayd (load balancer), tftpd, sshd, nfs, nsd and unbound (DNS) So, you could run an HTTPS site, with a Perl fastCGI site, sending emails, all out of Base Plus you get privsep'd X (xenocara)
Xenocara may not satisfy performance characteristics the way something like Wayland is. However, Xenocara is pretty awesome in (I believe) being the only X11 server to address the somewhat ugly security model of stuff running as root.
OpenBSD and performance are acquaintances, but not really close friends :)
