I have a standalone SQL Server, running SQL 2014 Standard. It is virtualized, running off VMWare. The box has ample resources (24 cores, and 192GB RAM, of which 128GB is allocated to MSSQL - maximum possible for Standard).Lately the index rebuild speeds have increased significantly. For example, a rebuild that normally took 35 minutes now takes 1 hour.I haven't made any changes to the environment. The data rate changes (that is, how much indexes become fragmented every day) has been relatively constant. The data set itself has grown, but not enough to double the time needed to rebuild the indexes.When index rebuilds execute, the server is otherwise idle.I've checked everything I could think of, but index rebuilds and performance thereof are a bit of a black box to me. Can anyone think of an obscure reason why the index rebuilds would suddenly take longer?
