Optimal my.cnf for IPB

[Owdy]

Are these settings okay?

#

# The MySQL database server configuration file.

#

# You can copy this to one of:

# - "/etc/mysql/my.cnf" to set global options,

# - "~/.my.cnf" to set user-specific options.

# 

# One can use all long options that the program supports.

# Run program with --help to get a list of available options and with

# --print-defaults to see which it would actually understand and use.

#

# For explanations see

# http://dev.mysql.com/doc/mysql/en/server-system-variables.html


# This will be passed to all mysql clients

# It has been reported that passwords should be enclosed with ticks/quotes

# escpecially if they contain "#" chars...

# Remember to edit /etc/mysql/debian.cnf when changing the socket location.

# * InnoDB

# InnoDB is enabled by default with a 10MB datafile in /var/lib/mysql/.

# Read the manual for more InnoDB related options. There are many!

There is no optimal my.cnf configuration for IPB. The optimal configuration will be different for each and every site, because it depends on how much data you have in your database and how much resources (memory, specifically) you have available on your server.

Assuming you have a dedicated server with 2GB of RAM and are using myisam tables, it looks alright to me. There are a couple of other variables I generally look to tweak, but overall it seems ok.
