From 965ffea43d4ebe8cd7b9fee78d651268dd7d23c5 Mon Sep 17 00:00:00 2001 From: Robert Olsson Date: Mon, 19 Mar 2007 16:29:58 -0700 Subject: [IPV4]: fib_trie root node settings The threshold for root node can be more aggressive set to get better tree compression. 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. --- net/ipv4/fib_trie.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/net/ipv4/fib_trie.c b/net/ipv4/fib_trie.c index 5d2b43d9f8fc..9be7da7c3a8f 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) -- cgit v1.2.3-59-g8ed1b
