Bug 6094 contains no additional information and there is not yet a
confirmed bug.

Your output indicates that there is a problem in your replication
setup and this is why the slave does not catch up.

This is not a performance issue. It is either a bug in replication, or
a user configuration issue. Since few things have changed in 9.1 in
this area, at the moment the balance of probability is towards user
error. If you can provide a more isolated bug report we may be able to
investigate.
