On the following page and in the example ini files installed with MySQL
it's suggested that key_buffer_size is an option that affects MyISAM
performance.
http://dev.mysql.com/doc/refman/5.0/en/server-system-variables.html
But on the following page about tuning MySQL server parameters, it says
"When tuning a MySQL server, the two most important variables to configure
are key_buffer_size and table_cache", with no mention of its applicability
to MyISAM or other types of tables.
http://dev.mysql.com/doc/refman/5.0/en/server-parameters.html
Does this option only affect MyISAM performance, or does it also affect
performance of operations on InnoDB tables?
