ReHi,
what exactly do you mean with "install a TPC-H database"?
I long have evidence that most people who talk about
benchmarks never really read any specs. This is not meant
personal against you or anyone else around here, but who here
ever read the TPC-C, -H or -W specifications? Neither the
pgbench we have, nor the FUD the MySQL lemmings love to
believe in has anything to do with the word benchmark.
Thus, asking for a TPC-H (the datawarehouse test suite) is
not bad. But one big mistake made over and over again is,
that people think TPC suites are database benchmarks. They
are NOT. In fact, they describe what the TPC calls a System
Under Test (SUT) on a business process level and a couple of
technical aspects for a possible implementation. What someone
finally uses to implement the described application, is up to
her.
So for the TPC-W for example, it is up to you if you
implement that entire book shop in PHP, J2EE, ASP, ADP or
CGI. You are free to use Apache, IIS, AOLServer, Tomcat or
any other thing that is intended to put out dynamic content
on port 80. The database behind it (if you use an SQL
database at all) is just one little piece of the entire SUT.
The result of the entire thing will NOT tell you MySQL is
faster than PostgreSQL (first because it's not, second that's
not what the test questions at all).
For more information you can find the specifications of all
the test suites on the website of the Transaction Processing
Performance Council
