Dm Query Taking Long Time

I'm running a query (see below) on my development server and its taking around 45 seconds. It hosts 18 user databases ranging from 3 MB to 400 MB. The production server, which is very similar but with only 1 25 MB user database, runs the query in less than 1 second. Both servers have been running on VMWare for almost 1 year with no problems. However last week I applied SP 2 to the development server, and yesterday I applied Critical Update KB934458. The production server is still running SQL Server 2005 Standard SP 1. Other than that, both servers are identical and running Windows 2003 Server Standard SP 1. I'm not seeing this discrepancy with other queries running against user databases.



use MyDatabase

GO

select db_name(database_id) as 'Database', o.name as 'Table',

s.index_id, index_type_desc, alloc_unit_type_desc, index_level, i.name as 'Index Name',

avg_fragmentation_in_percent, fragment_count, avg_fragment_size_in_pages,

page_count, avg_page_space_used_in_percent, record_count,

ghost_record_count, min_record_size_in_bytes, avg_record_size_in_bytes, forwarded_record_count,

schema_id, create_date, modify_date from sys.dm_db_index_physical_stats (null, null, null, null, 'DETAILED') s

join sys.objects o on s.object_id = o.object_id

join sys.indexes i on i.object_id = s.object_id and i.index_id = s.index_id

where db_name(database_id) = 'MyDatabase'
