| TPC-H Vesion 2 and Version 3 |
Over the past few years the industry has seen increases in performance and decreases in costs of computer and database systems. The TPC is introducing V3.0 of the TPC-H Benchmark to accommodate these trends and maintain the relevance of the Price/Performance metric. The primary change in this major revision is to adjust the Price/Performance metric by a multiplier of 1,000. The results shown for TPC-H V3 contain results that were converted from TPC-H V2 to the new specification. |
TPC-H is a Decision Support Benchmark |
|
The TPC-H is a decision support benchmark. It consists of a suite of business oriented ad-hoc queries and concurrent data modifications.
The queries and the data populating the database have been chosen to have broad industry-wide relevance. This benchmark illustrates decision support systems that examine large volumes of data,
execute queries with a high degree of complexity, and give answers to critical business questions. The performance metric reported by TPC-H is called the TPC-H
Composite Query-per-Hour Performance Metric (QphH@Size), and reflects multiple aspects of the capability of the system to process queries. These aspects include the selected database size
against which the queries are executed, the query processing power when queries are submitted by a single stream, and the query throughput when queries are submitted by multiple concurrent users.
The TPC-H Price/Performance metric is expressed as Price/QphH@Size for Version 2 and Price/kQphH@Size for Version 3. |
