improve view performance that use remote db

I have some views in my DW database that use some tables in the local db, and some from a production db. For my dev environment, I was using a copy of production db on the local server that hosts DW database. The view were performing pretty good in the dev environment. 

I recently moved the production db on a remote server to simulate production environment, and views now take much longer to run. The indexes are good, statistics updated.

What can be done to improve the performance of these views using database on remote server (linked server), without moving the DW database( that hosts views) to production server?

Thanks.
