How to add http proxy for apachebench(ab)

阅读更多关于 How to add http proxy for apachebench(ab)

问题 I want to grab http packets which ab sends or receives. So I add a http_proxy in shell command: $ export http_proxy=127.0.0.1:8888 Then I execute ab command: $ ab -c 1 -n 1 http://localhost/ Finally, my proxy(127.0.0.1:8888) failed to get http packets from ab. Is there any way to let ab access http via http_proxy? Here is my environment: Mac OSX 10.10.3 回答1: If you read about ab's help ab -h , you'll find that it supports an proxy option -X : -X proxy:port Proxyserver and port number to use

How do I fix “ssl handshake failed” with ApacheBench?

阅读更多关于 How do I fix “ssl handshake failed” with ApacheBench?

问题 When I use ApacheBench to test https, the error is returned, "ssl handshake failed". How can I use ApacheBench to test https? 回答1: ApacheBench doesn't seem to be capable of ignoring certificate problems (at least some of them) so I wrote this script: #!/bin/bash K=200; HTTPSA='https://192.168.1.103:443/' date +%M-%S-%N>wgetres.txt for (( c=1; c<=$K; c++ )) do wget --no-check-certificate --secure-protocol=SSLv3 --spider $HTTPSA done date +%M-%S-%N>>wgetres.txt It's not as precise as AB, but

问题 I'm creating a small server using java.nio , but when trying to stress test it I keep getting messages about the connection being reset on the server side, or more specifically: apr_socket_recv: An established connection was aborted by the software in your host machine I've tried to narrow it down to the most simple of loops, but still no luck. I can get the error after a hundred or so connections, or maybe just after 1 or 2. Here's the server loop: byte[] response = ("HTTP/1.1 200 OK\r\n" +

Tomcat response time is increasing as concurrency is increased in apache bench

阅读更多关于 Tomcat response time is increasing as concurrency is increased in apache bench

问题 When I am increasing concurrency -c in ab (apache bench) then I am getting different response time. -c 99% 3 2ms 5 4ms 8 6ms If I increase -c further then response time will increase as well.My code is extremely simple, No thread starvation, no blocking, etc. Then why the response time is getting increased? I think that ab -c 8 means 8 simultaneous request would be made to http://localhost:8070/benchmark . So is it possible that requests are getting pooled at tomcat? If it is so then how can

Apache自带的ab压力测试工具用法详解

阅读更多关于 Apache自带的ab压力测试工具用法详解

ab命令原理 Apache的ab命令模拟多线程并发请求，测试服务器负载压力，也可以测试nginx、lighthttp、IIS等其它Web服务器的压力。 ab命令对发出负载的计算机要求很低，既不会占用很多CPU，也不会占用太多的内存，但却会给目标服务器造成巨大的负载，因此是某些DDOS攻击之必备良药，老少皆宜。自己使用也须谨慎。否则一次上太多的负载，造成目标服务器直接因内存耗光死机，而不得不硬重启，得不偿失下载安装： http://mirror.bit.edu.cn/apache//httpd/binaries/win32/?C=M;O=A 找到 httpd-2.2.21-win32-x86-no_ssl.msi windows版本官方只提供源码，这里可参考下载：链接： https://pan.baidu.com/s/1ylrI7G5nSFu-LBlYgY0T3Q 提取码：uzmr 运行：在Windows系统下，打开cmd命令行窗口，定位到apache安装目录的bin目录下 cd C:\Program Files (x86)\Apache Software Foundation\Apache2.2\bin 键入命令： ab -n 800 -c 800 http://192.168.0.10/ （-n发出800个请求，-c模拟800并发，相当800人同时访问，后面是测试url）
