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.<\/p>\n
The same situation with PFSense 2.2.1 on a multicore server (Atom 8 cores) – server even hangs without any loads.<\/p>\n
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).<\/p>\n
Fix – add memory and mbclusters to a system:<\/p>\n
\/boot\/loader.conf<\/p>\n
vm.kmem_size=”1G”
\nvm.kmem_size_max=”2G”
\nkern.ipc.mbclusters=”1000000″
\nkern.ipc.nmbclusters=”262144″<\/p><\/blockquote>\n<\/p>\n","protected":false},"excerpt":{"rendered":"
