JQuery Ajax Chat Script - Questions about it

[TeddyKiller]

Sometimes the chatscript lags... it's very fast and efficient, but it uses a text file.

 

Sometimes it lags out for like.. 20 seconds maximum so far, but however.. not very often. Why does this happen, and how can it be prevented?

 

If I hooked the chatscript up to the database so it gets messages that way, would it be any slower? and if so.. how much slower. - Is it also the best method?

 

You can access the txt files outside of the chat, if txt files is the best solution, can this be prevented?

 

Thanks!
