WordPress Benchmark
OpenLiteSpeed vs. NGiNX vs. Apache
[/vc_column_text][vc_empty_space alter_height=”medium” hide_on_mobile=””][/vc_column][/vc_row][vc_row][vc_column][vc_column_text]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.
When it comes to WordPress, caching is important, so we made sure to use an appropriate caching solution for each web server in our tests.
All tests were performed with Keep-Alive enabled. (See more common settings under Web Server Configuration below.)[/vc_column_text][vc_empty_space alter_height=”medium” hide_on_mobile=””][/vc_column][/vc_row][vc_row][vc_column][vc_column_text]
The Results
The following charts show how many requests per second the three servers processed during our series of tests. The larger the number, the better.[/vc_column_text][vc_empty_space alter_height=”medium” hide_on_mobile=””][/vc_column][/vc_row][vc_row][vc_column width=”1/6″][/vc_column][vc_column width=”2/3″][vc_column_text]

In this test, we pair each server with an appropriate caching option.
As you can see, OpenLiteSpeed outperforms NGiNX and Apache in all of our scenarios.[/vc_column_text][vc_empty_space alter_height=”medium” hide_on_mobile=””][/vc_column][/vc_row][vc_row][vc_column][vc_column_text]
Try It Yourself
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.
This is the command we used in all tests (Replace example.com/path) with the location of your test subjects):
ab -n 10000 -k -H "Accept-Encoding: gzip,deflate" -c 100 example.com/path
Each test was run five times, and the average result was used for our graphs.[/vc_column_text][vc_empty_space alter_height=”medium” hide_on_mobile=””][/vc_column][/vc_row][vc_row][vc_column][vc_separator style=”dotted” border_width=”2″][/vc_column][/vc_row][vc_row gap=”35″ equal_height=”yes” content_placement=”middle”][vc_column][vc_column_text el_id=”web-server-config”]
