Web server benchmarking

Web server benchmarking is the process of estimating a web server performance in order to find if the server can serve sufficiently high workload.

Key parameters

The performance is usually measured in terms of:

Number of requests that can be served per second ;
Latency response time in milliseconds for each new connection or request;
Throughput in bytes per second.

The measurements must be performed under a varying load of clients and requests per client.

Tools for benchmarking

Load testing a web server can be performed using automation/analysis tools such as:

Apache JMeter, an open-source Java load testing tool
ApacheBench, a command line program bundled with Apache HTTP Server
Siege, an open-source web-server load testing and benchmarking tool
Wrk, an open-source C load testing tool
Locust, an open-source Python load testing tool

Web application benchmarks

Web application benchmarks measure the performance of application servers and database servers used to host web applications. TPC-W was a common benchmark emulating an online bookstore with synthetic workload generation.
