Adding key makes solution compile very slow

Hello,
        I am adding a strong name to my assemblies in order to work with Enterprise
Services' Transactions.
        When I add the strong name (with sn.exe -k), my compile time for a Rebuild
goes from 15 seconds to 3 minutes. This is for 1 solution with 11 projects.

Does anyone know if this is normal, or if there's an option to make it go
quicker?

Thanks,
Mark
