The DayZ Server documentation of BI says:
"reservedcores - number of CPU cores which will be used for other threads"
-> Do you mean "OTHER THREADS" by the OPERATING SYSTEM or the DEDICATED SERVER ?
-> There is no information to be found for the exact use of "RESERVERDCORES" in DAYZSETTINGS.XM anywhere on the internet!
-> IS "RESERVERDCORES" NEEDED FOR THE SERVER OR NOT ? CAN IT BE SET TO 0 ?
Setting 0 or any other number for RESERVERDCORES in DAYZSETTINGS.XML has no measurable effect on the server whatsoever.
The DayZ Server documentation of BI says:
https://community.bistudio.com/wiki/DayZ:Server_Configuration
XML Configuration
dayzsettings.xml
<jobsystem globalqueue="4096" threadqueue="1024">
<pc maxcores="4" reservedcores="1" />
<!--
maxcores - maximum number of CPU cores which will be used for jobsystem reservedcores - number of CPU cores which will be used for other threads number of worker threads is then "maxcores - reservedcores", but still at least one worker thread is allocated
-->
I mean DAYZSETTINGS.XML :-)
Oh and can you please update your documentation then ? :-D

It hasn't changed for many years anyway. ;-)
