UBB.threads PHP Forum Software Community Forums UBB.threads 6 Version 6 Support Indexing U_Number field

Hello.

We recently moved to a new server, and when we moved our databases over, MySQL put up a warning that we shouldn't have U_Number (in the Users databse) as both the primary key and index, so I took off the index. Was this the wrong thing to do? I think the boards have gotten sluggish since I did it.

Thanks,
Carl

A primary key is automatically indexed.
