- # This file describes how to run MySQL benchmark suite with PostgreSQL
- #
- # WARNING:
- #
- # Don't run the --fast test on a PostgreSQL 7.1.1 database on
- # which you have any critical data; During one of our test runs
- # PostgreSQL got a corrupted database and all data was destroyed!
- # When we tried to restart postmaster, It died with a
- # 'no such file or directory' error and never recovered from that!
- #
- # Another time vacuum() filled our system disk with had 6G free
- # while vaccuming a table of 60 M.
- #
- # WARNING
-
- # The test was run on a Intel Xeon 2x 550 Mzh machine with 1G memory,
- # 9G hard disk. The OS is Suse 7.1, with Linux 2.4.2 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.
- #
- # During the test we run PostgreSQL with -o -F, not async mode (not ACID safe)
- # because when we started postmaster without -o -F, PostgreSQL log files
- # filled up a 9G disk until postmaster crashed.
- # We did however notice that with -o -F, PostgreSQL was a magnitude slower
- # than when not using -o -F.
-
- #
- # First, install postgresql-7.1.2.tar.gz
-
- # Adding the following lines to your ~/.bash_profile or
- # corresponding file. If you are using csh, use ┤setenv┤.
-
- 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-1.18.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
-
- # When running with --fast we run the following vacuum commands on
- # the database between each major update of the tables:
- # vacuum anlyze table
- # vacuum table
- # or
- # vacuum analyze
- # vacuum
-
- # The time for vacuum() is accounted for in the book-keeping() column, not
- # in the test that updates the database.
-
- 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.
