The new setting mekes the root grow from 16 to 19 bits and substansial improvemnt in Aver depth this with the current table of 214393 prefixes But really the dynamic resize should need more investigation both in terms convergence and performance and maybe it should be possible to change... Maybe just for the brave to start with or we may have to back this out. --- diff --git a/net/ipv4/fib_trie.c b/net/ipv4/fib_trie.c index 5d2b43d9f8..9be7da7c3a 100644 --- a/net/ipv4/fib_trie.c +++ b/net/ipv4/fib_trie.c @@ -292,8 +292,8 @@ static inline void check_tnode(const struct tnode *tn) static int halve_threshold = 25; static int inflate_threshold = 50; -static int halve_threshold_root = 15; -static int inflate_threshold_root = 25; +static int halve_threshold_root = 8; +static int inflate_threshold_root = 15; static void __alias_free_mem(struct rcu_head *head)
