Date: Wed, 11 Mar 2015 16:28:50 -0400 (EDT) From: David Miller <davem@...emloft.net> To: alexander.h.duyck@...hat.com Cc: netdev@...r.kernel.org, stephen@...workplumber.org, jiri@...nulli.us, sfeldma@...il.com Subject: Re: [net-next PATCH] ipv4: FIB Local/MAIN table collapse From: Alexander Duyck <alexander.h.duyck@...hat.com> Date: Fri, 06 Mar 2015 13:47:00 -0800 > This patch is meant to collapse local and main into one by converting > tb_data from an array to a pointer. Doing this allows us to point the > local table into the main while maintaining the same variables in the > table. > > As such the tb_data was converted from an array to a pointer, and a new > array called data is added in order to still provide an object for tb_data > to point to. > > In order to track the origin of the fib aliases a tb_id value was added in > a hole that existed on 64b systems. Using this we can also reverse the > merge in the event that custom FIB rules are enabled. > > With this patch I am seeing an improvement of 20ns to 30ns for routing > lookups as long as custom rules are not enabled, with custom rules enabled > we fall back to split tables and the original behavior. > > Signed-off-by: Alexander Duyck <alexander.h.duyck@...hat.com> I've applied this, let's see what happens. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
