balancing

In computing, load balancing refers to the process of distributing a set of tasks over a set of resources (computing units), with the aim of making their overall processing more efficient. Load balancing can optimize the response time and avoid unevenly overloading some compute nodes while other compute nodes are left idle.
Load balancing is the subject of research in the field of parallel computers. Two main approaches exist: static algorithms, which do not take into account the state of the different machines, and dynamic algorithms, which are usually more general and more efficient, but require exchanges of information between the different computing units, at the risk of a loss of efficiency.

    I noticed that Rob gave someone some 'advice' on balancing their system. However it was rather 'quick and dirty' in my opinion. Is it worth creating a definitive guide that we could refer people to rather than have to type the same stuff over and over? To be honest there could be yet another...
