Draw Images Instantly	boolean	false (0)	TurboMode	Draw images instantly
Prefetch Web Fonts	integer	0	PrefetchWebFonts	Number of web fonts that may be prefetched. A non-zero value enables speculative prefetching of web fonts referred to by style sheets. When enabled pages using web fonts will generally be able to show content with the correct fonts earlier. However, there is a chance that style sheets refer to fonts that are never used, in which case unused fonts will get downloaded and load time increase.
Reflow Delay Load	integer	200	ReflowDelayLoad	Determines how often, in milliseconds, we aim to reflow the document while loading. Lower value means more "incremental" rendering, but slows loading down since we'll spend more time in total reflowing. If the value is zero, there will be no delay, which is not recommended for anyone. The appropriate value for this tweak depends largely on platform performance, and so is difficult to estimate accurately based on profile only. Testing and tuning "on device" while performing "average browsing" is typically very useful.
Reflow Delay Script	integer	500	ReflowDelayScript	Determines how often, in milliseconds, we aim to reflow the document while executing a script (usually the reflow would then be caused by the script.) Lower value means more "incremental" rendering, but slows down script execution since we'll spend more time in total reflowing. If the value is zero, there will be no delay.
Wait For Styles	integer	100	WaitForStyles	Determines how long we will hold the layout waiting for styles. This is to avoid drawing something unstyled (ugly)that will be replaced by something styled very soon. Setting this to 0 means that we won't wait for styles and instead show anything as fast as possible.
Wait For Web Fonts	integer	100	WaitForWebFonts	Determines how long we will suppress displaying web font text while waiting for the web font to load. This is to avoid drawing text with a fall back font that will later be replaced by a web font (FOUT). Setting this to 0 means that we will immediately display web font text using the fall back font. A non-zero value means that we won't display web font text until either the font is loaded or the time out expires and the fall back font is applied.
