You can find answers in this report.

While this is also written in Japanese, you can apply a machine
translator. You can copy and paste all sentences including texts in
the figure.

Rough summary of their considerations is...
 * Why the perf result of PostgreSQL decreased -> they had much
memories and high-performance CPU in 2012 compared to 2013.
 * Why the 4XCnode is much more than 4 times faster -> 4X cache
memories (sum of cache memory in all data nodes) gave such
improvement.
