Kerberos and performance

  • Does anyone know if Kerberos has a major performance cost whe it is used in cojunction with linked servers. I am told that there is a cost when using it with web servers but does the same apply when going between SQL & a linked server?

    Thanks for any info in advance.

  • I wouldn't say a major cost, but yes there is some cost associated with the connection. We use LMhosts (rather than DNS or Wins) and sql authentication (rather than Windows integrated) for all of our linked servers to reduce this as much as possible, and through testing have found it to be the best solution for our case. Of course, we take a hit in the "ease of management" catagory because of doing it this way.

  • Thank you for taking the trouble to reply.
