PFSense + FreeBSD + Multicore = ISSUE

I installed FreeBSD 10 on a multicore server and got strange behavior – network connections were slow and I got many timeouts with 1 client only.

The same situation with PFSense 2.2.1 on a multicore server (Atom 8 cores) – server even hangs without any loads.

The cause: the maximum of mbclusters were riched – 100% (PFSense – Dashboard), because they are dedicated by the system for the each core. There is no the issue on an one-two core system (enough).

Fix – add memory and mbclusters to a system:

/boot/loader.conf

vm.kmem_size=”1G”
vm.kmem_size_max=”2G”
kern.ipc.mbclusters=”1000000″
kern.ipc.nmbclusters=”262144″
