     You need _not_ to build custom FreeBSD kernel in order to increase
    NMBCLUSTERS. Both CURRENT and STABLE allows setting it from loader.conf:

    kern.ipc.nmbufs="32768" # Number of mbufs
    kern.ipc.nmbclusters="16384" # Number of mbuf clusters

    But yes, you have to reboot your system if you want to raise them.

    Sincerely, Dmitry
