Yes, it is necessary, if you have performance problem. LVS uses its own
simple and fast connection tracking for performance reasons, instead of
using netfilter connection tracking. So, it will not affect LVS, if
netfilter conntrack modules are not loaded.

LVS/NAT should work too without the conntrack modules.
