As has been discussed numerous times before and is a known fact - having a clustered index on a uniqueidentifier primary key column, in sql server,will affect performance.
What I would like to do is observe this issue by issuing inserts and measuring certain metrics. I have 2 tables with a uniqueidentifier PK; one with 'newid()' as the default and the other with 'newsequentialid()' as the default value. I plan to insert about a million rows in each and observe the INSERT performance.
What should I be querying for in particular? How can I best observe the performace gain of having sequential GUIDs over random GUIDs? Are there certain system views, stored procedures that give stats about the index page splits and/or other relevant information?
