vCenter 6.0 Appliance - Inventory Service using 45% of Available Memory

[sm7012]

vCenter 6.0  - 16 vCPUs /  60 gigs memory  .  When I run TOP I see the INVSVC using about 45 gigs of the Memory. (see below) .  Looking for any recommendations or settings I can check or verify to drop this number as the vCenter is running slow at times and hangs intermittently.

Connect to DB:

/opt/vmware/vpostgres/current/bin/psql -U postgres -d VCDB 

Run this below query:

SELECT nspname || '.' || relname AS "relation",

  pg_size_pretty(pg_total_relation_size(C.oid)) AS "total_size"

  FROM pg_class C

  LEFT JOIN pg_namespace N ON (N.oid = C.relnamespace)

  WHERE nspname NOT IN ('pg_catalog', 'information_schema')

   AND C.relkind <> 'i'

   AND nspname !~ '^pg_toast'

  ORDER BY pg_total_relation_size(C.oid) DESC

  LIMIT 20;

Also, attach vpxd, vpxd-profiler and invsvc logs.
