Also, you may need to raise hash table size. However, the lock is held per-instance. A cluster is linked list of mbufs keeping all data of single packet. It seems that disabling HT speeds up things a bit despite decreased number of queues. If that’s not enough for you, values can be set even bigger, just keep in mind that:

It seems that disabling HT speeds up things a bit despite decreased number of queues. For example, if you have 8 public adresses and need to NAT Complex configurations eats much more. Since you can easily get 16 different queues even for 8 for each port it is considerable to but core CPU like E Single mbuf takes bytes and mbuf cluster takes another bytes or more, for jumbo frames.

Say NO to i platform that greatly limits kernel virtual memory, move to amd Use tables, tablearg in every place you can. Juniper-like configs, multiple kernel tables, ability to filter kernel routes CategoryProject. This can affect you iff you’re doing shaping.

Also, you may need to freebsd hash table size. Default value causes routing software to fail with OSPF if jumbo frames is turned on. Avoid to use it.

Split out in per each inbound and outbound interface. RSS supports fgeebsd queues per port. Current netisr implementation can’t split traffic into different ISR queues patches are coming, It processes most packets falling back to ‘normal’ forward routine for fragments, packets with options, etc.

It is the easiest thing that can be offloaded without any problems.

Intel with non-Intel SFP+’s?

AMD seems to perform very bad on routing however I can’t prove it with any tests at the moment. Juniper-like configs, multiple kernel tables, ability to filter kernel routes CategoryProject NetworkPerformanceTuning last edited Default value is and is too low; you may want to increase it upto or more. Very small packets fit in one mbuf but more commonly, a packet consumes mbuf cluster plus one extra mbuf.

This is bad, but even worse is that e and maybe others unconditionally sets flowid to 0 effectively causing later hashing by netisr, of flowtable, or lagg, or.

If that’s not enough for you, values can be set even bigger, just keep in mind that: This permits later users like laggnetsr or multipath routing use existing data instead of hash calculations. Use as little number of rules as possible. But Intel NIC meet problem for managing interrupt storm during high pps throughput. Sendmsg cat’t freegsd messages more than maxdgram length. Note skipto tablearg works in O log nwhere n is number of rules, so it possibly can be used to implement per-interface firewall.

Good chipsets mixed with excellent drivers. No tcpdump, cdpd, lldpd, dhcpd, dhcp-relay. Do NOT use netisr policy other than ‘direct’ if you can.
