It's still useless because it tests a standalone backend, but at least the bit rot is repaired.

The Postgres Wisconsin Benchmark
|
|
|
|
The short form of the directions below:
|
|
|
|
ensure postmaster is stopped
|
|
export PGDATA=/wherever
|
|
make runtest
|
|
|
|
The long form:
|
|
|
|
In this directory are the queries and raw data files used to populate the
|
|
Postgres version of the Wisconsin benchmark. In order to run the benchmark,
|
|
you'll initially need to execute the script
|
|
|
|
./create.sh
|
|
|
|
which will populate the "bench" database, create the indices, and vacuum the
|
|
database. This will take from 10 minutes or so on a Sparc II/DECstation 5000
|
|
class machine to an hour on a Sun 3.
|
|
|
|
Once create.sh completes, you can execute the benchmark by running the
|
|
script
|
|
|
|
./runwisc.sh
|
|
|
|
into an output file. This output file may be quite large (300K or so)
|
|
so make sure you have sufficient disk space. Once the benchmark run has
|
|
completed, query execution times can be obtained by running the
|
|
|
|
./perquery
|
|
|
|
script on the output file. It will generate a nicely formatted, numbered
|
|
set of output with times for each query indicated. (Note that each query
|
|
is run twice.)
|
|
|
|
!!! WARNING! DO NOT RUN THESE SCRIPTS IF THE POSTMASTER IS RUNNING !!!
