order by killing me

sql2k sp2
Im aware that it normally slows everone down. But Ive got
a view, and when I select top 1 from it without an order
by it returns in 1 second. With order by takes over 4
minutes. Quite a jump. Ive got a Clustered Primary Key on
the column that Im ordering by. Any ideas?

What does the output from Query Analyzer > Show Plan indicate? How many rows
do you have?

Do the select statement with out Order by clause,Since you have primary key
on that field , automatically data will be arranged in that order. In this
case you do not require a order by clause.

For your information: if you want the rows of the resultset in a
particular order, you must specify an ORDER BY clause. Without it,
SQL-Server is at liberty to return the rows in any order it likes. At
one occasion this might accidentally be the order you desired, but at
another occasions a different order might result.
