There are multiple ways to perform load testing of webserver and websites. Most commonly used load testing are jmeter and ab benchmarking testing. We are going to explain on how to perform ab benchmarking load testing on a website.<\/p>\n

Assumption:<\/h4>\n
    \n
  1. We will perform ab benchmark testing on Ubuntu host. We can perform the same testing on Mac or any linux flavour as well. We need to install the ab <\/em><\/strong> utility on machine<\/li>\n
  2. Domain name or IP address which we want to perform Load test.<\/li>\n<\/ol>\n

    Performance Testing:<\/em><\/h4>\n

    Lets start with ab utility installation. Since, this post deals with Ubuntu host, use apt-get to install ab utility.<\/p>\n

    <\/code>apt-get -y install apache2-utils<\/code><\/p>\n

    The above command will install ab utility on the host.<\/p>\n

    Now, execute the ab benchmark command to get the stats.<\/p>\n

    ab -n 100 -c 10 http:\/\/domain.tld<\/code><\/p>\n

    where,<\/p>\n

    n – Number of requests to perform for the benchmarking session. The default is to just perform a\u00a0 single\u00a0 request\u00a0 which\u00a0 usually leads to non-representative benchmarking results.<\/p>\n

    c- Number of multiple requests to perform at a time. To load a single webpage, normally browser sends multiple request to serve a single page. In our example, we assumed that 10 request is being send to load the page.<\/p>\n

    The sample output<\/p>\n

    \n100%\u00a0\u00a0 6016<\/p><\/blockquote>\n

    From the above example, we can look Concurrency Level is 10 that means at a time, we are sending 10 concurrent connection.<\/p>\n

    The time taken for tests gives the output on how long does the benchmark utility takes to complete the test.<\/p>\n","protected":false},"excerpt":{"rendered":"
