從rafan那看來的一篇 stable mailing: “Tuning for router performance“，主要是提到有關em(4) & 5.3當router的一些調法
大概就是:
- if_em.h: EM_TIDV, EM_MAX_TXD, EM_MAX_RXD
- kern.random.sys.harvest.ethernet=0
- kern.random.sys.hervest.interrupt=0
- net.inet.ip.fastforwarding=1 (netinet/ip_fastfwd.c)
- net.ipc.nmbcluster 262144 ?!
- vm.kmem_size 跟 vm.kmem_size_max
- 把 em(4) 的 interrupt moderation 關掉：
