Can mixed collations affect performance?

I created a new server and database with a different default collation when I took over our small SQL Server environment. In transferring the objects from the existing server to the new production server, I used the scripts created by EM. For some reason, EM puts collation statements on all character based fields.

We connect to SQL Server from Access and for several months the applications would crawl. One night I came in and changed all of the collations to use the defaults. That morning the applications ran real fast and it still runs well. I may have done something else as a side consequence, but the only thing I remember is changing the collations.

Is this a known issue? I don't have the lab facilities to test it.
