I'm doing something like:
delete from table1 where id not in (select id from table2).
both id are indexed.
table1 contains ~1M record table2 contains ~ 600K record and id is
unique.
The box is a 2x dual core Xeon (below 2GHz) with 4Gb ram.
Default debian etch setup.
It has been working for over 2h now.
Is it normal?
