I don't know if I fully understand your question. So forgive me if
this isn't about what you asked.
When I upgraded from DB2 Connect V7 to V8 our DIST cpu went through the
roof. I opened an ETR with IBM. We found that our passwords were
being encrypted and the de-encryption is very expensive. The reason
our passwords were being encrypted was because of what I consider a bug
in the DB2 client.
I had my DB2 clients cataloged with the setting "Use authentication
value in server's DBM Configuration". On my DB2 Connect Server, I had
Authentication set to SERVER. Thus, my clients should be getting the
equivalent of "Server authentication". However, once your DB2 Connect
Server is becomes V8, you must actually set your clients to "Server
authentication (SERVER)", or else you will actually get SERVER-ENCRYPT.

Hope this helps,
