Web Load Testing Tools (3) web-bench

jason — Wed, 07 Jan 2009 02:16:16 +0000

Web Bench is very simple tool for benchmarking WWW or proxy servers. Uses fork() for simulating multiple clients and can use HTTP/0.9-HTTP/1.1 requests. This benchmark is not very realistic, but it can test if your HTTPD can realy handle that many clients at once (try to run some CGIs) without taking your machine down. Displays pages/min and bytes/sec. Can be used in more aggressive mode with -f switch.

INSTALL:

Web Load Testing Tools (2) siege

Siege is an http/https regression testing and benchmarking utility. It was designed to let web developers measure the performance of their code under duress, to see how it will stand up to load on the internet. It lets the user hit a web server with a configurable number of concurrent simulated users. Those users place the webserver "under siege." The duration of the siege is measured in transactions, the sum of simulated users and the number of times each simulated user repeats the process of hitting the server. Thus 20 concurrent users 50 times is 1000 transactions, the length of… Read the rest

Web Load Testing Tools (1) ab

ab is a tool for benchmarking the performance of your WWW HyperText Transfer Protocol (HTTP) server. It does this by giving you an indication of how many requests per second your Apache installation can serve.

Options

-A auth-username:password
Supply BASIC Authentication credentials to the server. The username and password are separated by a single : and sent on the wire base64 encoded. The string is sent regardless of whether the server needs it (i.e., has sent an 401 authentication needed).

-b windowsize
Size of TCP send/receive buffer, in bytes.

-c concurrency
Number of multiple requests… Read the rest
