 // PREF: notification interval (in microseconds)
+// When Firefox is loading a page, it periodically reformats
+// or "reflows" the page as it loads. The page displays new elements
+// every 0.12 seconds by default. These redraws increase the total page load time.
+// Lowering the interval will decrease the perceived page load time
+// but increase the total loading time.
 // The notification interval has a dramatic effect on how long it takes to
 // initially display content for slow connections. The default value
 // provides good incremental display of content without causing an increase
 // in page load time. If this value is set below 1/10 of a second it starts
 // to impact page load performance.
