\"Compare<\/a><\/p>\n

If our search statistics are any indication, the question on everyone’s mind is “How does OpenLiteSpeed compare to NGiNX and Apache?” We think that’s a question that deserves an answer, so we set up a test environment and got to work.<\/p>\n

Note:<\/strong> For a more in-depth discussion of the differences and similarities between LiteSpeed, Apache, and nginx, take a look at the comparison on our site<\/a>.<\/p>\n

The Contenders<\/h2>\n

We looked at OpenLiteSpeed, NGiNX, and Apache and we ran burst tests simulating 10,000 requests over 100 concurrent users. We looked at how the three web servers handled a small static file and a simple PHP script, and then we evaluated their WordPress performance.<\/p>\n

When it comes to WordPress, caching is important<\/a>, so we made sure to use an appropriate caching solution for each web server in our tests.<\/p>\n

All tests were performed with Keep-Alive enabled. (See more common settings under Web Server Configuration<\/strong> below.)<\/p>\n

The Results<\/h2>\n

The following charts show how many requests per second the three servers processed during our series of tests. The larger the number, the better.<\/p>\n

\"Compare<\/a><\/p>\n

Static files require no processing, and so this test is useful for measuring the servers\u2019 response times. How quickly can each server deliver small static files?<\/p>\n

\"Compare<\/a><\/p>\n

When we benchmark the “Hello World” PHP app, we are not testing real-world conditions. Nevertheless, this is the best way to isolate the communication<\/em> between server and PHP from the processing<\/em> of the PHP itself. With this test, what we are most interested in is how efficiently the server communicates with the PHP engine.<\/p>\n

\"Compare<\/a><\/p>\n

WordPress is a heavy PHP application and as such, caching is strongly recommended. In this test, we pair each server with an appropriate caching option.<\/p>\n

As you can see, OpenLiteSpeed outperforms NGiNX and Apache in all of our scenarios.<\/p>\n

Try it Yourself<\/h2>\n

In the interest of transparency, we’re including the specs of our web server configuration and test environment below. Feel free to run the same benchmarks and compare OpenLiteSpeed to NGiNX and Apache for yourself.<\/p>\n

This is the command we used in all tests (Replace example.com\/path<\/code> with the location of your test subjects):<\/p>\n

ab -n 10000 -k -H \"Accept-Encoding: gzip,deflate\" -c 100 example.com\/path<\/pre>\n
Each test was run five times, and the average result was used for our graphs.<\/p>\n
