Many people visiting the SQL Server booth wanted to know how to improve performance. With so much attention being given to COLUMNSTORE and in-memory tables and stored procedures, it is easy to overlook how important tempdb is to performance. Speeding up tempdb I/O improves performance. The best way to do this is to not do the I/O in the first place. With SQL Server 2014, tempdb page management is smarter. Pages are more likely to be released before being unnecessarily flushed to disk. Read more about it here.
Of course, not all tempdb I/O can be eliminated. Performance can be improved by moving database files to flash memory storage. To maximize the performance benefits of flash storage, buffer pool extensions should be enabled.
