We recently upgraded our servers to SQL Server 2014 from 2008 R2.There are a few processes which use linked servers to pull data across & the performance for most of these processes seems to be on par or slightly better than it was on the previous version.But there are others where the performance is horrible. On 2008, a specific linked server query took less than a minute to complete. Since moving over to 2014, it's taking longer than an hour.What we've done so far:Update stats with fullscanRecompiled objectsRebuilt indexesRecreated link serversIf you execute the query locally on the source server, it returns within seconds, so it's definitely something to do with the linked server setup.Anyone encountered something similar?
