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

The performance is usually measured in terms of:

• Number of requests that can be served per second (depending on the type of request, etc.);
• Latency response time in milliseconds for each new connection or request;
• Throughput in bytes per second (depending on file size, cached or not cached content, available network bandwidth, etc.).

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

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

• Apache JMeter, an open-sourceJava load testing tool
• ApacheBench (or ab), a command line program bundled withApache HTTP Server
• Siege, an open-source web-server load testing and benchmarking tool
• Wrk, an open-sourceC load testing tool^[1]
• Locust, an open-sourcePython load testing tool^[2]

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