How to install the NVIDIA drivers on Ubuntu 20.04 Focal Fossa Linux.And with this we have shown in a simple example how the Apache Bench tool can be used to gather statistics on the response time of our webservices. The static content is served much faster than the wasteful page that also need to go trough the php interpreter. It isn't a big surprise what the results show. Time per request: 0.351 (mean, across all concurrent requests) The second test will run with the same set of parameters, but against the wasteful php page index.php.Percentage of the requests served within a certain time (ms) Time per request: 0.196 (mean, across all concurrent requests) Licensed to The Apache Software Foundation,

$ ab -t 60 -n 100000 -c 10 This is ApacheBench, Version 2.3 <$Revision: 1826891Ĭopyright 1996 Adam Twiss, Zeus Technology Ltd, Also note that we eliminated true network traffic by benchmarking from localhost, and we push the load of both running the requests and serving them on the same hardware. On the lab machine this amount of requests will be served in one minute, but depending on the hardware this may not be sufficient. For the first test, we’ll run ab against the static page index.html, providing 100000 requests (-n) for the page in 10 concurrent threads (-c), within the maximum timeframe of 60 seconds (-t). We don’t need root privileges for benchmarking.We only create this page to see the difference in response times. Note that as we serve static text, we would only need one echo, or no php at all. We’ll add a static HTML page /var/The file will be /var/www/html/index.php, with the below content: \n".To create a test environment we’ll use our ab tool on, we’ll install a webserver with php support:.

To install Apache Bench, which is in the httpd-tools package, we’ll use dnf:.

To try out our tool, we’ll add some basic content to the webserver, both static and written in php.

How to run simple tests against the webserverĪpache Bench is available in the base software sources after enabling subscription management repositories along with the Apache httpd webserver.

How to install httpd webserver, and add some basic content.

In this tutorial we will install Apache Bench on Red Hat Enterprise Linux 8, as well as an Apache Webserver to run some tests against. With well-planned testing, this tool can show the possible bottlenecks of the application, and may provide points of interest where we should look into our code for possible optimization. Maybe before deploying a new version of the application, we could run the tests on the new version, and compare the results with the previous test data to see if our application will serve slower, or faster than the last version. While such simulated workloads will not result exactly the same data that real world traffic will do, it is always a good idea to test before going to production. We can specify the number of requests to send, the target URL, set up concurrency, just to name a few of this tool’s settings. Apache Bench is a useful little tool for testing the response time of a webservice, and thus the performance of the webserver.
