Explanation:
In an effort to simplify the tempdb configuration experience, SQL Server 2016 setup has been extended to configure various properties for tempdb for multi-processor environments.
1. A new tab dedicated to tempdb has been added to the Database Engine Configuration step of setup workflow.
2. Configuration options:
Data Files
Number of files - this will default to the lower value of 8 or number of logical cores as detected by

setup.
Initial size - is specified in MB and applies to each tempdb data file. This makes it easier to configure

all files of same size. Total initial size is the cumulative tempdb data file size (Number of files * Initial Size) that will be created.
Autogrowth - is specified in MB (fixed growth is preferred as opposed to a non-linear percentage based

growth) and applies to each file. The default value of 64MB was chosen to cover one PFS interval.
