| Measure the performance of your Web Server with Apache Benchmark Posted: 21 May 2011 11:00 PM PDT Free Software -
MANY tool that can be used to measure the performance of the web server, one of them by using the web stress tool for windows. But can also use the APache Benchmark (AB) from the Apache HTTP Server is one of the widely used web server on the internet.This is the Apache Benchmark tool to measure the performance of apache, with ab we can see the capabilities of apache to serve the request from the client. But the question is we often discover about apache benchmark is how do I install and where to download the apache benchmark.
AB has installed automatically when installing the Apache HTTP Server, if apache already installed then the benchmarking tool is also already automatically exists. This is usually the location tool ab in-directory. Apache benchmark Tool can be used not only for the Apache web server, but for others as well as the Lighthttpd, Nginx or Miscrosoft IIS.
How to use AB is as follows:
# ab-n 1000-c 1000 ' http://202.xxx.xxx.xxx/mongotest/comment/get_data/20/10 '
-The Parameter c is the number of concurrent (simultaneous) requests are made, with the example above means the number of request that is created is 1000 request in one time.
-The Parameter n is the number of connections made to the server, with the example above means that the connection is made is 1,000 connections. This consumes resource server Ab, ranging from memory (RAM), bandwidth and processor. Enter the number of connections and the appropriate request conccurent, so that the web server not to run out of resource and then hang.
-The last Parameter is the URL, the page will be processed by the web server in the-benchmark.
Example of benchmark results as follows:
[root @ monggo-lho-mas ~] #/usr/local/apache2/bin/ab-c 1000-n 1000 ' http://202.xxx.xxx.xxx/mongotest/comment/get_data/20/10 '
This is ApacheBench, Version 2.3 < $ Revision: 655654 $ >

Apache benchmark is a pretty good tool, the result is quite informative. Apache benchmark can be used to supplement the results of the benchmarks used by other tools.
