# 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 vacuuming 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-

2.tar.gz
# Adding the following
lines to your ~/.bash_profile
or
# corresponding
file.
If you are
using csh, use ´setenv´.

include
export POSTGRES_LIB=/usr/

#
#
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/

chown postgres /usr/

exit

# Second, install packages DBD-Pg-

# Now we
run the test that can be found

# When running with --fast we run the following vacuum commands on

# vacuum analyze table
# vacuum table

# vacuum analyze

# The time for vacuum() is accounted for in the book-keeping() column, not
# in the test that updates the database.

# 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

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