DAX co-processors are not used when queries are running with In-Memory tables on SPARC T7-1 server

Hello,

We have SPARC T7-1 server, Solaris 11.3 (SRU 6.5)

Schema DUMMY was created by TPC-H DBgen 2.17.0 utility with SF=300 (approx 300Gb).

No indexes and constraints, all tables accepted INMEMORY attribute, so only FULL INMEMORY SCAN were observed in execution plans.

But all DAX counters are zeroes.
