How "Firewall Maximum Table Entries size" correspond or depend to total amount of avail for FreeBSD system memory?

How "Firewall Maximum Table Entries size" value correspond or depend to total amount of avail for FreeBSD system memory ?

Please point me on a source where described in details how important for network operations resources like

• NICs controllers (CPU, memory on controllers, number of Eth ports on each controller);
• whole appliance memory amount;
• main appliance CPU;
  and
  memory/network/cpu core settings in FreeBSD;

influence on pfSense speed, troughtput and stability of operation.

Common words are less interesting than numbers, of course :)

Thank You!
