skusim byt konkretnejsi v "radach". Toto su nastavenia z niektorych nasich 
strojov. Avsak, treba sa na to pozerat v kontexte hardverovej konfiguracie 
tj. najma napr. velkost RAM atd.

#; defaults to 400 MB
#; echo "vm.kmem_size=1G" >> /boot/loader.conf

#; defaults to 384
echo "kern.maxusers=512" >> /boot/loader.conf

#; defaults to 25600, see `netstat -m`, calculate as (net.inet.tcp.sendspace 
+ net.inet.tcp.recvspace) * max concurent connections * 2 [in 2kB blocks]
echo "kern.ipc.nmbclusters=65536" >> /boot/loader.conf

#; defaults to 128, see `netstat -Lan`
echo "kern.ipc.somaxconn=8192" >> /etc/sysctl.conf

#; this defaults to 25600
echo "kern.ipc.maxsockets=131072" >> /etc/sysctl.conf

#; this defaults to 262144
echo "kern.ipc.maxsockbuf=524288" >> /etc/sysctl.conf

#; this defaults to 12328/11095
echo "kern.maxfiles=131072" >> /etc/sysctl.conf
echo "kern.maxfilesperproc=100000" >> /etc/sysctl.conf

#; this defaults to 32768/65536
echo "net.inet.tcp.sendspace=131072" >> /etc/sysctl.conf
echo "net.inet.tcp.recvspace=131072" >> /etc/sysctl.conf

#; this defaults to 0
echo "net.inet.tcp.nolocaltimewait=1" >> /etc/sysctl.conf
