Re: Which memory settings to change?

InnoDB ONLY: 70% for innodb + a few MB for key_buffer
OR
MyISAM ONLY: 0 for innodb + 25% for keybuffer (leaving extra for OS to cache data blocks)
OR
Both engines: some compromise.

Do not allocate so much space that MySQL is being swapped.

Depending on the OS, MySQL code, etc, leave perhaps 1GB outside the above caches.
