postgresql

Hi,

I'm doing massive tests on a Postgres database...

so basically I have 2 table where I inserted 40.000.000 records on, let's say table1 and 80.000.000 on table2

after this I deleted all those records.

Now if I do SELECT * FROM table1 it takes 199000ms ?

I can't understand what's happening?

can anyone help me on this?
