Hi, Maxime

During the 18.05-rc1 performance testing, I find this patch set will bring
slightly performance drop on mergeable and normal path, and big performance
drop on vector path. Could you have a check on this? I know this patch is 
important for security. Not sure if there is any way to improve the performance.
