# 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 <20>setenv<6E>.
