Changing POST data used by Apache Bench per iteration

阅读更多关于 Changing POST data used by Apache Bench per iteration

问题 I'm using ab to do some load testing, and it's important that the supplied querystring (or POST) parameters change between requests. I.e. I need to make requests to URLs like: http://127.0.0.1:9080/meth?param=0 http://127.0.0.1:9080/meth?param=1 http://127.0.0.1:9080/meth?param=2 ... to properly exercise the application. ab seems to only read the supplied POST data file once, at startup, so changing its content during the test run is not an option. Any suggestions? 回答1: You're going to need

问题 I am just start using AB just today. Read couple of AB tutorial on new and thought give it a try for load testing my site. After using it couple of time I got huge number of failed request. Can you explain what is mean by a failed request? How can I investigate more for this issue?

问题 Below is a apache bench run for 10K requests with 50 concurrent threads. I need help understanding the results, does anything stand out in the results that might be pointing to something blocking and restricting more requests per second? I'm looking at the connection time section, and see 'waiting' and 'processing'. It shows the mean time for waiting is 208, and the mean time to connect is 0 and processing is 208..yet the total is 208. Can someone explain this to me as it doesn't make much

Does Node.js perform badly on Windows, surely it can't be slower than apache for basic I/O

阅读更多关于 Does Node.js perform badly on Windows, surely it can't be slower than apache for basic I/O

问题 Question: Are the result that i'm getting reasonable? Is there anything which could have such an impact in reducing the number of requests per second? Edit: A friend of mine has just benchmarked the same application on Linux and the average r/s was approx 7000. Edit #2: I've checked the CPU usage of Node.exe, and it's only using 5-6% of the cpu. Surely this figure should be 12% on a quad core machine, 8 thread CPU when running on a single thread if truly under load? I've written a Node.js

问题 I'm trying to write an extremely simple concurrent server in Rust to play with the language's concurrency primitives and its threading model. Here's my code: use std::io::prelude::*; use std::io::Result; use std::net::{TcpListener, TcpStream, Shutdown}; use std::sync::{Arc, Mutex}; use std::thread; fn handle_client(mut stream: TcpStream) -> Result<()> { try!(stream.write(b"HTTP/1.0 200 OK\r\nContent-Type: text/plain\r\nContent-Length: 5\r\n\r\nPong!\r\n")); // try!(stream.shutdown(Shutdown:

（总结）Web性能压力测试工具之ApacheBench（ab）详解发表于: Linux , Web , Web Server , 个人日记 , 原创总结 | 作者: 博客教主标签: ab , ApacheBench , Web , 压力测试 , 工具 , 性能 , 总结 , 详解 PS：网站性能压力测试是性能调优过程中必不可少的一环。只有让服务器处在高压情况下才能真正体现出各种设置所暴露的问题。Apache中有个自带的，名为ab的程序，可以对Apache或其它类型的服务器进行网站访问压力测试。 ApacheBench命令原理： ab命令会创建很多的并发访问线程，模拟多个访问者同时对某一URL地址进行访问。它的测试目标是基于URL的，因此，既可以用来测试Apache的负载压力，也可以测试 nginx 、lighthttp、tomcat、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，既不会占用很高CPU，也不会占用很多内存，但却会给目标服务器造成巨大的负载，其原理类似CC攻击。自己测试使用也须注意，否则一次上太多的负载，可能造成目标服务器因资源耗完，严重时甚至导致死机。 ApacheBench参数说明格式：ab [options] [http://]hostname[:port]/path 参数说明： -n requests Number of

How to add http proxy for apachebench(ab)

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

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 ahuigo 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 This option is equivalent of curl 's -x : -x, --proxy [PROTOCOL://]HOST[:PORT] Use proxy on given port
