From eeb1b73378b560e00ff1da2ef09fed9254f4e128 Mon Sep 17 00:00:00 2001 From: Steffen Klassert Date: Fri, 25 Oct 2013 10:21:32 +0200 Subject: xfrm: Increase the garbage collector threshold With the removal of the routing cache, we lost the option to tweak the garbage collector threshold along with the maximum routing cache size. So git commit 703fb94ec ("xfrm: Fix the gc threshold value for ipv4") moved back to a static threshold. It turned out that the current threshold before we start garbage collecting is much to small for some workloads, so increase it from 1024 to 32768. This means that we start the garbage collector if we have more than 32768 dst entries in the system and refuse new allocations if we are above 65536.
