Hi CAO Admin,
The board will only work as well as the server it's hosted on. Are you on a dedicated or shared plan? Slow-down could be caused by different variables, directly dealing with the server. Variables such as disk space, server memory, board usage (members, posts, overall traffic).
If we could get a demo login account so we can take a look at the size of the board, it would help us determine what may be causing the lag. Also what are your board stats (posts, members, pageviews, etc.)?
Thanks,
