The performance of WD does not change for a long time and it is well understood for a long time too. I remember several threads about it. All operations related to tasks with
many executables (copying, moving, archiving, backups, opening big folders first time after reboot) have poor performance because the files are re-checked by WD. There are also known methods to improve the performance by using Windows Policies or excluding folders. These performance issues are reflected in the left part of the performance table included in the report:

The right part of the performance table includes the tasks that consume 99% of average users' activities. In these tasks, Microsoft is as fast as the "lightest" Avs. If the user is focused on the tasks from the left part of the performance table, then he/she feels WD as slow - otherwise, the performance is usually great.
On some computers WD is slow without a visible reason. This is not necessarily related to poor resources.
Shortly, for most users WD has poor performance in %1 and great performance in 99%. Still, its performance is below average, because most AVs has even better performance during 1% of time.
