Re: Performance downgrade and essential tables have been splitted into two !!!
I don't know why your performans problem, but I know _LOC and _NLS tables; You know after 8.0 version PPM has been multilanguage, so you have a local texts and other language texts. Thus LOC mean local text, _NLS mean national texts.
