Web Stress Testing

Use Webbench,webbench on Linux to simulate up to 30,000 concurrent connections to test the load capacity of a website

Installation steps:
Tar zxvf webbench-1.5.tar.gz
CD webbench-1.5
Make &&make Install

Stress test:
Webbench-c 500-t http://10.10.8.73/
-C 500 is a concurrent number
-T 30 for continuous time

[Email protected] ~]# netstat-an |grep "Time_wait" |wc-l
27994

The test results show that there are 27,994 time_wait

Optimize the kernel:

Check the current value of NET.IPV4.TCP_TW and change the current value to 1 minutes:
[Email protected] ~]# Sysctl-a|grep NET.IPV4.TCP_TW
Net.ipv4.tcp_tw_reuse = 0
net.ipv4.tcp_tw_recycle = 0

Vi/etc/sysctl
Add or modify the NET.IPV4.TCP_TW value:
Net.ipv4.tcp_tw_reuse = 1
Net.ipv4.tcp_tw_recycle = 1

Make kernel parameters effective
Sysctl-p
