Tune the database size and layout:
The TPC-E database consists of several file groups, and it can vary between different benchmark kits. Size is measured in number of customers, and for the database to be auditable, the ratio of database size (customers) to throughput (tpsE) should be approximately 500.
You can perform more fine tuning on the database layout :
Database tables that have higher access frequency should be placed on the outer edge of the disk if rotational disks are used.
The default TPC-E kit can be changed, and new file groups can be created. That way, file groups can consist of higher frequency access table(s) and they can be placed on the outer edge of the disk for better performance.
