Would too many SqlTableProfileProvider items impact performance?

Hi all,

I'm using the SqlTableProfileProvider to handle my profile information. I have a table ProfileTable with a primary and foreign key UserId (1-to-1 relationship with aspnet_Users).

Right now I have A LOT of profile information (81 columns to be exact). Because I'm using SqlTableProfileProvider, I have  define all the fields in my web.config like such:
<profile enabled="true" defaultProvider="TableProfileProvider">
        <add name="TableProfileProvider"
             type="Microsoft.Samples.SqlTableProfileProvider"
             connectionStringName="MySqlServer"
             table="ProfileTable"
   &nb ...
