Workload
Go for industry benchmarks… Like TPC
The TPC Benchmark™H (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.
TPC Benchmark C is an on-line transaction processing (OLTP) benchmark. TPC-
C is more complex than previous OLTP benchmarks such as TPC-A because of
its multiple transaction types, more complex database and overall execution
structure. TPC-C involves a mix of five concurrent transactions of different types
and complexity either executed on-line or queued for deferred execution. The
database is comprised of nine types of tables with a wide range of record and
population sizes. TPC-C is measured in transactions per minute (tpmC).
