<h1 id="how-to-improve-the-performance-of-a-friendica-site">How to improve the performance of a Friendica site<a class="headerlink" href="#how-to-improve-the-performance-of-a-friendica-site" title="Permanent link">#</a></h1>
<p>Feel free to ask in the <a href="https://forum.friendi.ca/profile/helpers">Friendica support forum</a> if you need some clarification about the following instructions or if you need help in any other way.</p>
<h2 id="system-configuration">System configuration<a class="headerlink" href="#system-configuration" title="Permanent link">#</a></h2>
<p>Please go to /admin/site/ on your system and change the following values:</p>
<div class="highlight"><pre><span></span><code>Set &quot;JPEG image quality&quot; to 50.
</code></pre></div>
<p>This value reduces the data that is sent from the server to the client. 50 is a value that doesn't influence image quality too much.</p>
<div class="highlight"><pre><span></span><code>Set &quot;OStatus conversation completion interval&quot; to &quot;never&quot;.
</code></pre></div>
<p>If you have many OStatus contacts then completing of conversations can take some time. Since you will miss several comments in OStatus threads, you maybe should consider the option "At post arrival" instead.</p>
<div class="highlight"><pre><span></span><code>Enable &quot;Use MySQL full text engine&quot;
</code></pre></div>
<p>When using MyISAM (default) or InnoDB on MariaDB 10 this speeds up search.</p>
<h2 id="addons">Addons<a class="headerlink" href="#addons" title="Permanent link">#</a></h2>
<p>Active the following addons:</p>
<div class="highlight"><pre><span></span><code>rendertime
</code></pre></div>
<h3 id="rendertime">rendertime<a class="headerlink" href="#rendertime" title="Permanent link">#</a></h3>
<p>This addon doesn't speed up your system.
It helps to analyze your bottlenecks.</p>
<p>When enabled you see some values at the bottom of every page.
They show your performance problems.</p>
<div class="highlight"><pre><span></span><code>Performance: Database: 0.244, Network: 0.002, Rendering: 0.044, Parser: 0.001, I/O: 0.021, Other: 0.237, Total: 0.548
Database: This is the time for all database queries
Network: Time that is needed to fetch content from external sites
Rendering: Time for theme rendering
Parser: The time that the BBCode parser needed to create the output
I/O: Time for local file access
Others: Everything else :)
Total: The sum of all above values
</code></pre></div>
<h2 id="apache-webserver">Apache Webserver<a class="headerlink" href="#apache-webserver" title="Permanent link">#</a></h2>
<p>The following Apache modules are recommended:</p>
<h3 id="cache-control">Cache-Control<a class="headerlink" href="#cache-control" title="Permanent link">#</a></h3>
<p>This module tells the client to cache the content of static files so that they aren't fetched with every request.
Enable the module <code>mod_expires</code> by typing in <code>a2enmod expires</code> as root.
Please add the following lines to your site configuration in the "directory" context.</p>
<div class="highlight"><pre><span></span><code>ExpiresActive on ExpiresDefault &quot;access plus 1 week&quot;
</code></pre></div>
<p>Also see the Apache <a href="http://httpd.apache.org/docs/2.2/mod/mod_expires.html">2.2</a> / <a href="https://httpd.apache.org/docs/2.4/mod/mod_expires.html">2.4</a> documentation.</p>
<h3 id="compress-content">Compress content<a class="headerlink" href="#compress-content" title="Permanent link">#</a></h3>
<p>This module compresses the traffic between the web server and the client.
Enable the module <code>mod_deflate</code> by typing in <code>a2enmod deflate</code> as root.</p>
<p>Also see the Apache <a href="http://httpd.apache.org/docs/2.2/mod/mod_deflate.html">2.2</a> / <a href="https://httpd.apache.org/docs/2.4/mod/mod_deflate.html">2.4</a> documentation.</p>
<h2 id="php">PHP<a class="headerlink" href="#php" title="Permanent link">#</a></h2>
<h3 id="fcgi">FCGI<a class="headerlink" href="#fcgi" title="Permanent link">#</a></h3>
<p>When using Apache think about using FCGI.
In a Debian-based distribution you will need to install the packages named <code>php5-cgi</code> and <code>libapache2-mod-fcgid</code>.</p>
<p>Please refer to external documentation for a more detailed explanation how to set up a system based upon FCGI.</p>
<h3 id="database">Database<a class="headerlink" href="#database" title="Permanent link">#</a></h3>
<p>There are scripts like <a href="http://www.day32.com/MySQL/">tuning-primer.sh</a> and <a href="http://mysqltuner.pl">mysqltuner.pl</a> that analyze your database server and give hints on values that could be changed.</p>
<p>Please enable the slow query log. This helps to find performance problems.</p>
