You are _vastly_ over-tuning, IMO. Do you actually have empirical evidence that each of the settings you are changing is actually yielding a net overall improvement?
Are you actually using MyISAM? Are you _sure_ that enlarging join_buffer_size is helping in your case? Query cache is almost always harmful if you have done your real optimisation appropriately. Is that mysqltuner output you pasted? It is a downright dangerous tool that far too often gives cripplingly terrible advice.
