I have a big table too, about 16GB.
It is a vert static one(customer table), will add data
once in it, but queried all the time, and do the
segmentations against it all the time.
It also has 12 indexes. Right now , the performance is
ok. Any special consideration for such a big table.
Thanks,
Harvest.
