Data locality with Nutanix and Postgres DB migration

In this video I migrate a Postgres DB running PGbench benchmark. The DB is running on a Host which is CPU constrained. Once the VM is migrated to a less busy host the transaction rate immediately increases from ~15,000 to ~20,000. As the DB continues to run on the new host - the Nutanix storage detects the access patterns and "localizes" the data that the DB is accessing. Over the subsequent minutes the transaction rate increases to ~30,000 TPS.
