Hello guys,

Im looking for some information about jail resource. For example: how many cores and memory jail using when i have created a jail and set nothing just default settings ? How many cores jail will use when i compile some soft from ports ? Server has 4 cores, 8 threads nad 16GB ram.

Thanks !
 
Thanks Ver :D

But i have a one jail and i start compile soft from ports so how many cores will be used default ?
 
Hanging threads like this bug me, so I'll add a hopeful answer. I am using iocell and it seems the resource limits per jail can be set via iocell set (https://iocell.readthedocs.io/en/stable/basic-use.html#set-property) but I haven't tested it yet.

The complete answer on how to limit jail resources is (unsurprisingly) in the handbook:
https://www.freebsd.org/doc/handbook/security-resourcelimits.html

And the man page for rctl
https://www.freebsd.org/cgi/man.cgi?rctl

I'll update the thread if I get around to testing it.
