SWAP usage always zero



  • I have a pfSense box running the latest version with 3 GB of memory and the SWAP usage never moves of 0%.

    Memory usage is also hangs at 13%.  Maybe I should move 1GB of RAM to some other machine.  :-)

    Installed packages Lightsquid, mailreport, ntop, OpenVPN Client, RRD Summary, snort, squid3.

    Thnx,

    -TAC



  • Ideally you should never have swap usage on a firewall, but if you're hanging out at 10% usage, you probably could unallocate some VM memory. Don't forget, a state consumes about 1KiB of memory and each connection has 2 states. Just make sure you have enough memory to handle your maximum number of states. 1KiB per state, 2 states per connection.
