Select from view takes too long - sql

Question

I have a query against a table that contains like 2 million rows using linked server.
Select * from OPENQUERY(LinkedServerName,
'SELECT
PV.col1
,PV.col2
,PV.col3
,VTR.col1
,CTR.col1
,PSR.col1
FROM
LinkedDbName.dbo.tbl1 PV
INNER JOIN LinkedDbName.dbo.tbl2 VTR
ON PV.col_id = VTR.col_id
INNER JOIN LinkedDbName.dbo.tbl3 CTR
ON PV.col_id = CTR.col_id
INNER JOIN LinkedDbName.dbo.tbl4 PSR
ON PV.col_id = PSR.col_id
WHERE
PV.col_id = ''80C53C9B-6272-11DA-BB34-000E0C7F3ED2''')
That query results into 365 rows and is executed within 0 second.
However when I make that query into a view it runs for about minimum of 20 seconds and sometimes it reaches to 40 seconds tops.
Here's my create view script
CREATE VIEW [dbo].[myview]
AS
Select * from OPENQUERY(LinkedServerName,
'SELECT
PV.col1
,PV.col2
,PV.col3
,VTR.col1
,CTR.col1
,PSR.col1
FROM
LinkedDbName.dbo.tbl1 PV
INNER JOIN LinkedDbName.dbo.tbl2 VTR
ON PV.col_id = VTR.col_id
INNER JOIN LinkedDbName.dbo.tbl3 CTR
ON PV.col_id = CTR.col_id
INNER JOIN LinkedDbName.dbo.tbl4 PSR
ON PV.col_id = PSR.col_id')
then
Select * from myview where PV.col_id = '80C53C9B-6272-11DA-BB34-000E0C7F3ED2'
Any idea ? Thanks !

Answer 1

Your queries are quite different. In the first, the where clause is part of the SQL statement passed to OPENQUERY(). This has two important effects:
The amount of data returned is much smaller, only being the rows that match the condition.
The query can be optimized with the WHERE clause.
If you need to share the table, I might suggest that you make a copy on the local server -- either using replication or scheduling a job to copy it over.
