SQL Server 2014 Performance Enhancements
Database Performance has become an important subject for any database administrator, database Analysts and IT Directors. That is why Microsoft has focused on the performance factor within SQL Server 2014 to achieve 10x-30x improvement without touching your code whatsoever, they did that through in-Memory OLTP with no page buffer. Then you can create memory optimized table and add it to a memory optimized file group which is translated to .dll entry points. Moreover its data is more resilient, in other words its data remains intact after a server crash as they look like resident on disk. Awesome! I don’t have enough words to say how much it improved significantly an OLTP transaction to insert and delete 1 million records from 32 sec to just 2 seconds! In addition you no longer worry about heavy delete processes used for archiving because records are actually not deleted but just marked as deleted and another garbage collection process will take place asynchronously to clean up the deleted data without affecting on live transactions. Additionally, no changes are needed from developers on code level as it is one of the major myths of in-memory OLTP technology
This dream of performance was achievable through in-memory OLTP and other important projects targeted at rebuilding the architecture of the SQL engine….read full article here
