I don't it's a negative point, but the application persistence will be a
good feature for LVS because realservers know all clientes will be a
performance penalty.
My problem is because I am using IIS servers in my realservers and they
need some database or another procedure to save sessions of all clients.
I will take a look about memcached in Windows.
