Dynamic Font rendering performance issues on iOS
This test project renders a string of N random characters every frame.
Testing on an iPad 2 with a string of 30 characters the font generation step would take 70ms. It becomes slower as more characters are added to the string.

I have the same problem as THINKYHEAD_. I have a UI Text element that gets updated whenever my game's score changes. I'm using a Canvas set to "Scale With Screen Size" (with the iPhone 5C's resolution as reference), which means that my font size needs to be set to 120-140 in order to be visible on the 5C. With some fonts, the game completely stalls for a fraction of a second when updating the Text element. With other fonts, the stalling is more sporadic. Reducing the font size gets rid of the problem, but the text becomes too small to read.

Using a dynamic font for a loading screen - takes approximately 2s on an iPad 2 to to render when SetActive is called.

Perhaps related, I have a set of several GUIText objects where I'm changing the text periodically in 25 of them, running on an iPad 3. Whenever these GUITexts are changed there's a complete stall in the Unity App. This stalling, often a half second or more, almost always occurs. I had been trying to also do animation by increasing the font size in a GUIText and although it nearly worked, I experienced stalls and even more pronounced effects such as all the other GUITexts on the screen glitching for a second.
