<h1>Parameters<a class="headerlink" href="#parameters" title="Permalink to this headline">¶</a></h1>
<p>Varnish Cache comes with a set of parameters that affects behaviour and
performance. Parameters are set either though command line
arguments to <code class="docutils literal notranslate"><span class="pre">varnishd</span></code> or at runtime through <code class="docutils literal notranslate"><span class="pre">varnishadm</span></code> using
the <code class="docutils literal notranslate"><span class="pre">param.set</span></code> CLI command.</p>
<p>We don’t recommend that you tweak parameters unless you’re sure of what
you’re doing. We’ve worked hard to make the defaults sane and Varnish
should be able to handle most workloads with the default settings.</p>
<p>For a complete listing of all parameters and their specifics see
<a class="reference internal" href="../reference/varnishd.html#list-of-parameters"><span class="std std-ref">List of Parameters</span></a>.</p>
