Performance.lua and add these lines tot he very end:

function TitanPanelPerformanceButton_OnClick()
collectgarbage('collect')
end

Next, open TitanPerformance.xml, and where the </onload> tag is, add under it:

<OnClick>
TitanPanelPerformanceButton_OnClick();
</OnClick>

Now whenever you left click on the performace Buttom/text, you will force a garbage collection.

Cheers.

Thanks to taffu and Cladhaire who gave me a indirect general idea on how to do this. Also Tristanian @ WoWUI.IncGamers for the xml
