# of milliseconds before entering timeout poll This setting should be left at 250 (or higher). It is also meant to "tweak" certain outlier situations.<br>
Background:
</p>
<ul>
<li>
On Windows, a sleep call can take 15 ms. This could potentially cause each Lua call to take 15 ms.
</li>
<li>
Some pages / templates will call Lua hundreds of times. (For example: the Weather Box on <a tabindex="-1" href="/site/en.wikipedia.org/wiki/Aruba">http://en.wikipedia.org/wiki/Aruba</a> or the Citations on <a tabindex="-1" href="/site/en.wikipedia.org/wiki/Earth">http://en.wikipedia.org/wiki/Earth</a> )
</li>
<li>
The busy wait is a primitive way to limit a wait to 1 ms (or less) before entering a more expensive sleep
</li>
<li>
A higher timeout busy wait value is more performant, but the disadvantage is that the UI will be locked up for longer
</li>
</ul>
<dl>
<dd>
For example, a busy wait of 250 means that the code will loop for 250 milliseconds before entering a sleep.
</dd>
<dd>
For sub-second values, this freezing will be unnoticeable
</dd>
</dl>

For reference, here is the corresponding code

This setting should be left at 250 (or higher). It is also meant to &quot;tweak&quot; certain outlier situations.

Background:
</p>
<ul>
<li> On Windows, a sleep call can take 15 ms. This could potentially cause each Lua call to take 15 ms.
</li>
<li> Some pages / templates will call Lua hundreds of times. (For example: the Weather Box on <a href="/site/en.wikipedia.org/wiki/Aruba" tabindex="-1">http://en.wikipedia.org/wiki/Aruba</a> or the Citations on <a href="/site/en.wikipedia.org/wiki/Earth" tabindex="-1">http://en.wikipedia.org/wiki/Earth</a> )
</li>
<li> The busy wait is a primitive way to limit a wait to 1 ms (or less) before entering a more expensive sleep
</li>
<li> A higher timeout busy wait value is more performant, but the disadvantage is that the UI will be locked up for longer
</li>
</ul>
<dl>
<dd> For example, a busy wait of 250 means that the code will loop for 250 milliseconds before entering a sleep.
</dd>
<dd> For sub-second values, this freezing will be unnoticeable
</dd>
