SQL Server itself should have enough memory to cache your entire
database in memory. For 8000 users, you should have a dedicated
SQL Server box with atleast 128 megs of memory and SQL Server
allowed to use about 90-100 megs of that.
I am also working on a multi-threaded RadiusNT that has multiple
SQL Server connections and can handle quite a bit higher load than
the current one can. In you current situation, you should look into
two or three RadiusNT servers, to split the load across.
