説明

In PowerShell repo we started porting Microsoft.PowerShell.LocalAccounts module to System.DirectoryServices.AccountManagement API (from p/invokes). We had to use workarounds because Principal.FindByIdentity() methods is extremely slow - up to 100x(!) vs Principal.PrincipalSearcher().

On my notebook Get-LocalUser name ported cmdlet takes 2.8 sec(!) vs 25 ms if a workaround is used.
