What is “Audit Logout” in SQL Server Profiler?

Question

I\'m running a data import (using C#/Linq), and naturally I\'m trying to optimize my queries as much as possible. To this end I\'m running a trace on the DB using SQL Serve

Login/Logout events are related to the setting up / tearing down. IIRC the time is the 'was logged in for time' as opposed to a processing duration as with other log events.

In general, one hides these events unless you suspect there's an issue with connection pool management etc.

The raw times for the batches should be sufficient to diagnose the time the actual activity is taking including the impact of any transactions etc.
