用pktgen发包。我测过,可以跑到970多M

TCP 能到 850Mbps
udp 只有 1.05Mbps
但是考虑到可能是iperf的udp测速本身不完美(比如自己实现的包确认机制之类),于是再开openVPN over
UDP,在此基础上跑用iperf测TCP速度,也只有 350Mbps左右,跑的时候CPU都没有满因此不太可能是openVPN的瓶颈。
Linux的UDP协议栈的确不是为大数据量优化的,速度很受限制

目前已经证实的问题是,网卡的质量很重要.
破解就不要来这里问了吧。
sysctl 把buffer开大一点。在国内到荷兰的622M 专线上,350ms延迟,UDP可以跑到512Mbps+,iperf测试,丢包<0.01%,基于debian2.6标准内核。
