MyBB Community Forums

I have one query regarding the forums performence.. I am expecting a good load on the forum once I put it in my site..something around 100 users at a time and more then 20000 users. So will it be able to handle that mush load. If anybody suggest me the bandwidth required for this load that will be a great help to me.

thanks and regards,

The code is written for the best performance possible (I remember a Developer posting this but cannot find the post at this time). Only server load and bandwidth will be an issue.
Having a robots.txt file and blocking unnecessary pages and images will help reduce bandwidth use from bots.
