The changes are autocalculated according to a combination of RAM and OS bit-width (32 vs. 64). Performance will increase, more so with more RAM. Documentation on these settings has ranged from sparse to none over many years. The early Microsoft documents used in the calculations appear completely gone, there are some new ones. The settings produced by OWTAS have undergone testing over the last ten years, on a wide variety of Wintelamd platforms, and appear to work well on all. .PRIVATEDATA #> <# .DESCRIPTION OWTAS - enhances performance by adding threads.
