Set innodb_buffer_pool_size to 70% of _available_ RAM if you are using InnoDB entirely (and little or no MyISAM).

32-bit OS will restrict each program (eg mysqld) to 3GB or maybe 2GB.

If the server is running only MySQL, then 70% of RAM. If you are running a bunch of other things, then compensate for them.

If innodb_buffer_pool_size is set "too high", the OS will start "swapping". This is more detrimental than setting innodb_buffer_pool_size smaller.
