If I query the same machine via WMI using a forward-only ManagementObjectSearch the performance is great (1000/sec). I don't see any similar options on the EventLogReader (e.g. ReturnImmed...

Now obviously this does not currently work, so I'm attempting to create a "generic" backup process that allows us to backup and restore our data on Server 2000 and up (since SQL2000 is the least common denominator of all or customers). Right now ...
