I have a table which includes 78 fields. I have a query : "select * from this_table where id=X" which I call from perl application. After I load about 40000 rows into this table, this query runs very slow. How can I fix it?

Thanks.

If it is a join, place the table having lots of rows at the end of the FROM-clause. Make some index of the primary keys.
