Q: Performance Mode fails on 10.11 Server/5.0.4 Server App
After having upgraded some servers to 10.11 El Capitan with Server.app 5.0.4, I realized performance mode was disabled on all of them. Trying to enable it again just returns:
bash-3.2# serverinfo --setperfmode 1
ERROR: Server performance mode could not be modified.
Failed to create write propery list to disk!
Any ideas why this doesn't work any longer? Why can't it write the plist when sudo:ed? This was also a bug in 9.0.0 Server with upgraded systems.

OK. Got an official answer from our technical contact at Apple (we are Apple consultants): Servers doesn´t need SIP. Turn it off.
"sudo nvram boot-args="srv=1"" doesn't do "all the stuff" that "serverinfo--setperfmode 1" does, so use the latter.
