<h4>TART - Tab Animation Regression Tests</h4>
<div id="hide-during-run">
Visit <a href="https://wiki.mozilla.org/Performance_sheriffing/Talos/Tests#TART">talos/TART</a> for detailed info.<br/>
<ul>
<li><b>If you just opened the browser</b> - give Firefox few seconds to settle down before testing.</li>
<li><button onclick="setASAP()">Set ASAP mode</button> <button onclick="unsetASAP()">Restore default</button> (requires restart to take effect). TART runs best (and in talos) with vsync disabled - to measure maximum throughput (ASAP mode). This means the preferences layout.frame_rate = 0 and docshell.event_starvation_delay_hint = 1</li>
<li>In talos, TART runs with a single tab. If you wish to test a specific animation with several tabs open, you can do so as well by manually opening few tabs before starting the test.</li>
</ul>
