I think with PostgreSQL 9.6, the OLTP workloads (short queries) will see a major performance improvement for both read-write as well as read-only workloads mainly due to below features (there could be others as well, but this is what comes to my mind first):
Replace shared-buffer header spinlocks with atomic operations to improve scalability
Partition the freelist for shared hash tables, to reduce contention on many-CPU servers
Reduce contention for the ProcArrayLock
Where feasible, trigger kernel writeback after a configurable number of writes
Increase the number of clog buffers for better scalability

I think we should add that as a significant change.
