"Load balancing" is short hand for "give each server an appropriate
If you have two servers, one "twice as powerful" as the other, the

The appropriate load is to send as much traffic to each server as it
can efficiently handle.
For most applications the primary resource constraint is either
memory or CPU. In either case you figure out how many simultaneous
