How big ARC systems > nowadays? How big benefit did you measured there from THP? Hardware support for THP on ARC is relatively recent - as part of newly announced HS38x cores. So we don't have silicon yet to measure the performance benefits. I'm currently testing this on our nsim simulator but we are slated to get silicon with this pretty soon. If you were surprised by this you will likely be more with my highmem / PAE40 support patches which I will send out early next week ;-) Customers these days want more future safety, if nothing else and these features were added per more of them wanting these in their designs.
