<h2 id="performance-measures">Performance measures</h2> <p>Performance measures include elapsed time of the test, the amount of data transferred (including headers), the response time of the server, its transaction rate, its throughput, its concurrency and the number of times it returned OK. These measures are quantified and reported at the end of each run.<a class="footnote-ref" id="fnref:3" href="#fn:3"><sup>3</sup></a> </p><p>This is a sample of siege output: </p> Ben: $ siege -u shemp.whoohoo.com/Admin.jsp -d1 -r10 -c25 ..Siege 2.65 2006/05/11 23:42:16 ..Preparing 25 concurrent users for battle.

It can read a large number of URLs from a configuration file and run through them incrementally (regression) or randomly (internet simulation). Or the user may simply pound a single URL with a runtime configuration at the command line (brute force).<a class="footnote-ref" id="fnref:4" href="#fn:4"><sup>4</sup></a> </p> <h2 id="platform-support">Platform support</h2> <p>Siege was written on <a href="/facts/Linux/9FvCKSTq">Linux</a> and has been successfully ported to <a href="/facts/IBM_AIX/cRWERua2">AIX</a>, <a href="/facts/Berkeley_Software_Distribution/XQKcURrh">BSD</a>, <a href="/facts/HP-UX/hIvLDdJF">HP-UX</a>, and <a href="/facts/Solaris_(operating_system)/KPfT98EJ">Solaris</a>.
