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
TOP图
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:
Test Execution (Endpoint 1 to Endpoint 2)
Group/ Pair | Endpoint 1 | Endpoint 2 | Network Protocol | Service Quality | Script/Stream Name |
---|---|---|---|---|---|
All Pairs | |||||
Pair 1 | 192.168.10.249 | 192.168.100.24 | TCP | Throughput.scr |

关于si 、ksoftirqd 等这里就不作解释。
50k 条规则测试 测试主机ACCEPT 在最后一条,ixchariot 测试结果:

Totals: | 78.976 | 60.286 | 94.787 |
服务器性能:
把测试主机放在第一条时测试:
无论是 30k规则还是50k规则
Measured Time (secs) < 15 secs
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!
