![]() ![]() This proper calculation derives an actual Fill factor value which need to be applied on the table. Before setting the Fill Factor we need to analyse the Datatype of columns, actual cell size of the rows, Average number of rows in the pages and estimated updated size of row cell. In most cases SQL Server index Fill factor will help to get well performed when Table having large number of rows and frequent update over the rows. In this example we have used 80% Fill Factor, however it doesn’t make sense to push without any benchmarking for the table. To quote from SQL Server Index Fill factor with a Performance Benchmark: Increasing the fill factor would degrade performance for these tables. Many tables in AX have a large number of rows and experience frequent updates. index fill factor: I wouldn't change this setting without having a good reason to do so.Now, in your question you mention two separate points: Changing a setting just because it seems a good idea is not a good idea. You should have a good performance monitoring in place that tells you how things have changed after you changed a setting. It is far easier to make things worse than it is to make them better. If you do SQL Server performance optimization, you should know what you are doing.9 times out of 10, it is an issue with application, data or layer 8, but not the database. First check should always be in the application where the bottleneck is. AX performance issues rarley come down to database performance issues.So be aware of this when reading the rest of this answer. I would consider myself on the AX expert side of things and have enough SQL Server knowledge to be dangerous (or to get by). Database performance tuning for AX in my experience requires the intersection of two expertises (AX and SQL Server) that rarely exist in one person. ![]()
