[置顶] iptables 性能 测试

时间:2023-11-22 20:36:38

一直研究iptables 性能,这几天刚好有硬件资源,于是发始下手测试iptables NAT 性……

硬件环境  :

服务器: IBM x3650 ( 4G  E5645 6核 12线程) ESXi

测试服务器  : Ser1 配置 ( 1.5G 4核心 redhat 6.2 x64 iptables v 1.4)

测试服务器  : windows xp (512内存,2核心 ),Endpoint 用

网络环境  :Gbps

测试软件:业界公认的Ixchariot

NAT FORWARD 默认为DROP

生成测试所需要的 iptables 规则,下面贴出生成iptables 脚本:

#!/bin/bash
###
##regard
#default output iptables policy file name is "iptables_policy",Please completed renamed
#default output mac bandding file name is "mac_policy",please completed renamed
###
start_ip=1
end_ip=3000
ip_n=0
## ip_n is subnet [ example 192.168.iP_n.x ] ###----------------------------------------------------------------------------
### PRIGRAM
###---------------------------------------------------------------------------- ##############
while [ $start_ip -le $end_ip ]
# echo "[ $start_ip -gt $end_ip ]"
do
if [ $start_ip -eq 254 ]
then
ip_n=$(($ip_n + 1))
start_ip=1
end_ip=$(($end_ip - 253))
#reserve end_ip.254 (SSH control port)
fi
iptables -A FORWARD -i eth0 -s 192.168.$ip_n.$start_ip -m state --state NEW,ESTABLISHED,RELATED -j ACCEPT
echo "#arp -i" '$in_net' " -s 192.168.$ip_n.$start_ip " >> mac_policy
##display
echo "#iptables -A FORWARD add 192.168.$ip_n.$start_ip [OK] ; arp -i [ interface ] -s 192.168.$ip_n.$start_ip [OK] "
start_ip=$(($start_ip + 1 ))
done

30k 条规则测试 测试主机ACCEPT 在最后一条,ixchariot 测试结果:

说明iptables 规则顺序与延时有极为重要的关系,稍后附测试数据,与NetBSD 的PF 性能,敬请关注!
