If we make "bigger" documents (1000 or more signs, tables with 20 to 40 rows or so) the performance for each input is very slow (a delay of 10, 20 seconds from typing to show in the editor). We have this effect in our application but similar in the demo of your website, with ie 7.0 and firefox without bigger differences, same with deactivated firewall/antivirus ...)
What we (or you) can do for better performance?
thanks & best regards
