this would be even faster:

truncate table {objectQualifier}eventlog

You can do that from Host > SQL

Eric,

It's exectly what I've done manually.

My point is that PurgeEventLog SP doesn't do automatically due to timeout, what it is suppose to do. The SQL seems too slow:

DELETE FROM dbo.dnn_EventLog

FROM dbo.dnn_EventLogConfig elc
WHERE
    (
    SELECT COUNT(*)
    FROM dbo.dnn_EventLog el
    WHERE el.LogConfigID = elc.ID
      and dbo.dnn_EventLog.LogTypeKey = el.LogTypeKey
      and el.LogCreateDate >= dbo.dnn_EventLog.LogCreateDate
    ) > elc.KeepMostRecent
AND elc.KeepMostRecent<>-1
 
 Should I raise suggestion for optimization in Geminy?

I am not sure if the SQL has been fix in later versions of DNN. But I've just read the article http://weblogs.asp.net/omarzabir/archive/2007/10/16/cleanup-inactive-anonymous-users-from-asp-net-membership-tables.aspx that uses select top N to make deletion time manageable:

-- No of users to delete per run. If it's too high, database will get stuck

   6: -- for a long time. If it's too low, you will end up having more trash than
   7: -- you can cleanup
   8: DECLARE @NoOfUsersToDelete int
   9: SET @NoOfUsersToDelete = 1000
select top(@NoOfUsersToDelete)
