# This file describes how to run MySQL benchmarks with Postgres
# 

# The test was run on a Intel Xeon 2x 550 Mzh machine with 1G memory,
# 9G hard disk.  The OS is Suse 6.4, with Linux 2.2.14 compiled with SMP
# support
# Both the perl client and the database server is run
# on the same machine. No other cpu intensive process was used during
# the benchmark.

#
#
# First, install postgresql-7.1.1.tar.gz

# Adding the following lines to your ~/.bash_profile or
# corresponding file. If you are using csh, use īsetenvī.
#

export POSTGRES_INCLUDE=/usr/local/pg/include
export POSTGRES_LIB=/usr/local/pg/lib

PATH=$PATH:/usr/local/pg/bin
MANPATH=$MANPATH:/usr/local/pg/man

#
# Add the following line to /etc/ld.so.conf:
#

/usr/local/pg/lib
and run ldconfig.

# untar the postgres source distribution,  cd to postgresql-*
# and run the following commands:

CFLAGS=-O3 ./configure
gmake
gmake install

mkdir /usr/local/pg/data
chown postgres /usr/local/pg/data
su - postgres
/usr/local/pg/bin/initdb -D /usr/local/pg/data
/usr/local/pg/bin/postmaster -o -F -D /usr/local/pg/data &
/usr/local/pg/bin/createdb test
exit

#
# Second, install packages DBD-Pg-1.00.tar.gz and DBI-1.14.tar.gz,
# available from http://www.perl.com/CPAN/

export POSTGRES_LIB=/usr/local/pg/lib/
export POSTGRES_INCLUDE=/usr/local/pg/include/postgresql
perl Makefile.PL
make
make install

#
# Now we run the test that can be found in the sql-bench directory in the
# MySQL 3.23 source distribution.
#
# We did run two tests:
# The standard test

run-all-tests --comment="Intel Xeon, 2x550 Mhz, 512M, pg started with -o -F" --user=postgres --server=pg --cmp=mysql

# and a test where we do a vacuum() after each update.
# (The time for vacuum() is counted in the book-keeping() column)

run-all-tests --comment="Intel Xeon, 2x550 Mhz, 512M, pg started with -o -F" --user=postgres --server=pg --cmp=mysql --fast

# If you want to store the results in a output/RUN-xxx file, you should
# repeate the benchmark with the extra option --log --use-old-result
# This will create a the RUN file based of the previous results

run-all-tests --comment="Intel Xeon, 2x550 Mhz, 512M, pg started with -o -F" --user=postgres --server=pg --cmp=mysql --log --use-old-result
run-all-tests --comment="Intel Xeon, 2x550 Mhz, 512MG, pg started with -o -F" --user=postgres --server=pg --cmp=mysql --fast --log --use-old-result

# Between running the different tests we dropped and recreated the PostgreSQL
# database to ensure that PostgreSQL should get a clean start,
# independent of the previous runs.
