+LoadTest (stress test)
-* 20 @font-face rules per page is pretty scalable. When you scroll the page or do some action during the downloading and rendering of a font, rendering will take a lot more time. So if more than 50 @font-face rules are used, it would take too much time for a user to wait (nearly 10 seconds, but not measured)
+* On Windows, it seems even more scalable. A web page with 100 @font-face rules will be loaded in around 1 second. But when more than 150 @font-face rules are used in a single page, it takes much more time to load. A web page with 200 @font-face rules will be loaded in around 20 seconds, which is a lot more than that on Mac.
 * It does not crash even if a page had more than 1000 @font-face rules, but it would take more than 5 minutes until the text is rendered, which is not endurable for general use.
-** The more @font-face rules you have in a page, the more time is needed to its rendering. It seems that the time it takes is O(n^2) or something

 * What happens if I use multiple unicode-range rules to consist a single font-family?
 ** ex. @font-face{ font-family:testA; src:url(fontA.ttf); unicode-range:U+0-U+2FF; } @font-face{ font-family:testA; src:url(fontB.otf); unicode-range:U+300-U+FFF }
-* What happens if I specified only a single character in @font-face { font-family:smallA; src:url(smallA.ttf); unicode-range:U+1; } and tried to display a letter like this? &lt;span class="font-family:smallA"&gt;ABC&lt;/span&gt;?
+* What happens if I specified only a single character in the rule and tried to display other character? Would there be a fallback function?
