Does the D&D4e Character Sheet lag for anyone else?

I personally don't experience it, but my players say that the D&D4e character sheet lags pretty badly. Edit: I'm thinking that it has to do with the sheer size of the D&D4E sheet. It's 1.3MB and ~22000 lines of code. The next one that even comes close to that is the D&D5E sheet which is 291KB and ~5500 lines of code. I've cut that down to 720 KB by cutting the number of powers down from 100 to 50, but that still puts the sheet a good 400 KB ahead of anything else. When downloading a file 400 KB isn't much, but I assume that the Roll20 character sheet environment is different.

I have not had issue with it personally, but it could be due to your player's system/connection.

yep, only a little bit, I've actually had it crash my browser once or twice

Its render lag, its due to the dynamic way the very large amount of html is loaded. I can't do much about it without loseing functionality.

If the powers were changed back to a repeating field, would this cut down on the lag? What else, if anything, would be lost other than the ability to use them as token actions? For example, would it be possible to keep the new UI, attack/damage bonus, etc.
