Thanks, so nCBs will always be greater than nFEs?

Thanks, I have activated -auditlog on one of our servers to see the
impact on the fileserver. Quite a lot of information - unfortunately
this requires a restart of the file server to de-/activate. It seems the
content is similar to FileLog after sending one TSTP to the fileserver,
but with a bit more information on transactionsans slightly easier to
parse.

Thats the plan to get a feeling for the base line utilization; I also
plan to monitor GotSomeSpaces.

Best regards
