Native vs. SQL: The Delta
Early versions of SQL Server option for Microsoft Dynamics NAV (then called Navision) didn’t scale up as high as one would expect. Although SQL Server itself could scale up to thousands and tens of thousands of concurrent users, running a production environment of an ERP system is way different from running generic lab tests.
SQL Server 2000 brought many improvements, and finally outperformed Navision Database Server at any level of user concurrency. SQL was gaining momentum, and became the platform of choice for new implementations of Navision. When SQL Server 2005 came out, and when support for it was included in Microsoft Dynamics NAV 4.0, it could outperform the native database platform as much as 35%.
