One possiblility is to change the PK to nonclustered and the index on
[Date] to clustered. If you often do range/grouping queries based on
[Date] then that should be useful, but it might also impact queries
using TroubleshootId, so you need to test any change with a number of
representative queries.
Other general advice would be to review the query plan in QA (Ctrl+K),
run UPDATE STATISTICS on the table, and also try tracing a typical
workload and running it through the Index Tuning Wizard to see what it
can recommend.
If you need more specific comments, you should post the query plan
(using SET SHOWPLAN_TEXT), and it might also be useful to know how many
rows are returned by the query.
