The swap issue is explained in the excellent article by Jeremy Cole at the Swap Insanity and NUMA Architecture. Make sure the drives are mounted with noatime and also if the drives are behind a RAID controller with appropriate battery-backed cache. There is an issue with this, which causes the OS to swap even with memory available.

Because microprocessors are so fast, computer architecture design has evolved towards adding various levels of caching between compute units and the main memory, in order to hide the latency of bringing the bits to the brains. This avoids thrashing caches too much for B and evens out the pressure on the L3 caches of the machine.
