![]() ![]() The table below is designed to avoid reaching the maximum level of hardware load, so as not to run into problems. ![]() For higher throughputs we strongly advise you to follow the sizing suggested by the following table, based on tests actually performed in the field. If less than 10 Mbps are required then the minimum hardware requirements can be used. It is important to determine the throughput of a network before installing a pfSense/OPNsense firewall / router as it determines the type of CPU to use and in some cases the type of NIC. If instead we have to create a Router that joins networks together we have to sum up the throughput of all the interfaces, both WAN and LAN. It will therefore be necessary to consider the overall throughput of the system we want to achieve for the choice of the apparatus.įor example, if we need to build a firewall, we can consider the sum of the WAN throughputs as throughput. Throughput is the amount of data transmitted in a unit of time and depends exclusively on how much information is entered on the transmission channel.īefore considering throughput considerations, we need to consider the fact that both pfSense and OPNsense can operate both as a firewall and as a router or both. ![]() Both capacity and throughput are expressed in bit / s, but while the first expresses the maximum transmission frequency at which data can travel, throughput is an index of the actual use of the link capacity. Throughput is not to be confused with link capacity. Required throughputīy definition, throughput of a communication channel is meant its transmission capacity actually used. These 3 factors mainly affect RAM, CPU, mass memory and NIC quantities.Īlso keep in mind that from version 2.4 pfSense does not support systems on CF anymore (in particular it no longer supports i386 images), which OPNsense still supports them.
