Query plan re-use on views?

Here's the setup:

Client database has a complex view with eight nested subqueries used to return "dashboard" information. The application code uses NHibernate to call and filter the view with three parameters, one of which is the CustomerID.

A certain customer, (the biggest client), has more than ten times the number of records of the next largest customer.

Occasionally, the database reaches a state where when this particular customer tries to run the dashboard view, the application times out.

If I open up the view and re-save it, all is well again for a few days.

What gives?

Views are supposedly not pre-compiled, though I know that 2000 stores bits and pieces of query plans.

Any ideas on what causes this and what to do about it?are you experiencing large amounts of new data on a regular basis throwing off statistics and fragmenting your indices. just cuz they ain't precompiled don;t mean that they do not use that stuff right?|||No. Loaded a ton of historical data when the app was first installed, but inserts have been slow and steady since then.
