The website was updated today with a fix that should fix the AIML import performance problem.
A few other AIML fixes where added as well, and the Self AIML syntax was simplified.
Note that the max memory size for a bot is 100,000 items, which your bot currently exceeds. It is ok to go above the limit, but your bot will forget its least referenced data during the night, which could affect your AIML scripts. You can get bigger memory sizes on Paphus Live Chat http://www.paphuslivechat.com
