an older machine:
2005 thinks it has 1Gb and 1 cpu on a host which has 2GB, 2 2.4Ghz Amd64's,
raid0. it runs in boosted priority when active.
2000 is on an older single Amd64 2Ghz, 1Gb, single sata drive.
A very ugly query built by selections on a web page is parsed and
parameterized.
on 2000 it runs in a couple seconds against a few thousand rows joining lots
of tables, varying by the selections made.
on 2005 it takes twice as long for the identical query. all other software
variables are identical. the db is a copy from 2000. stats updated. tried
with both compatibility levels.
I'm thinking I'll wait for 9.1 or 9.2 before I make the move.br (br@.discussions.microsoft.com) writes:

Before you do that... The database on SQL 2005, is that a copy of the
database from SQL 2000? In such case, did you run UPDATE STATISTICS
WITH FULLSCAN on all table (or just sp_updatestats if you prefer)? When
you restore a database from SQL 2000, all statistics are invalidated,
this can be an important reason for difference in performance.

Express edition is limited by design to 1 CPU, 1 GB RAM, and 4 GB database
size.
There are server and database configuration settings that can impact
performance:

It's the developer version. Roughly equivalent to standard.
The stats are updated.
I'm figuring I'll have to re-optimize for 2005, so I don't mind waiting for
a fix rev or two.
But thanks for the links. I'll check them out.

PC ?). There may be VM session settings limiting RAM and CPU usage. Also,
SQL Server is optimized to work directly with the OS and hardware, and a VM
session is an abstraction layer.
