Performance problems with query

Guys,
I'm stumped. While its not pertinent to the
matter, we are running a Vignette content management
system on Win2k with Sql 2000 Enterprise on a cluster.
The server has 2 Gig of RAM , 2 CPU's and the database
size is 1.5G.
The query below is fired at login. The indexes
seem fine based on the query plan. When I look through
profiler, the query below takes a very high # of CPU
cycles and reads. It consistently takes more than 1.5
seconds to execute the query below. I did a dbcc pintable
for ALL the tables in the query and that did not help
either. It seemed to make it worse (3 seconds and above)
Any idea what could be the issue here? The server
is not really heavily taxed.
The tables are small. They have very few rows.
VGNCCB_ROLE 939
VGNCCB_ROLE_JT 62389
VGNCCB_GROUP_USER_JT 1364
The problem Query:
select
ROLE_ID,
NAME,
DESCRIPTION,
CREATE_DATE,
MODIFIED_DATE
FROM
vign.VGNCCB_ROLE -- Clustered Indexed on Role ID
WHERE
ROLE_ID in
(select ROLE_ID
FROM
vign.VGNCCB_ROLE_JT -- Non clustered indexes
on USER_NAME AND non clustered on GROUP_ID
WHERE
USER_NAME = 'testRole' or GROUP_ID in (select
GROUP_ID
FROM
vign.VGNCCB_GROUP_USER_JT -- Non clustered
index on USER_NAME
WHERE
USER_NAME = 'testRole'))
I'd appreciate it if someone could follow me in this
thread to completion. Such a simple query should not take
this long.
TIA,
Jack
