>I have a log file that contained 78K records. I deleted like 55 K records from it. Mind you it is not indexed, etc, it is not even part of a DBC. Now it takes for ever (3 à 4 seconds to open, or to do anything with it). It is opened shared.
It seems this is related to an external problem. This table is really small. Do you have corrupted tags? Do you have memo fields?
