Database Speed

Hey everyone,

I will be creating two wordpress sites very soon and I am trying to decide on the best database setup.

If I install both sites in the same data base but use different prefixes for each site, will it effectively be as if I installed each site in its own database in terms of speed?

Basically, the sites have very large databases so I need all of the extra speed I can get; however, if there is no negative impact on speed, I would like the sites to share users - hence the same database.

Thanks for any feedback

It is better is to start both blogs in different database, instead of using one database

Absolutely use two databases.

How they can share same users if they have different table prefixes.

What are the advantages of using two different database?
