I'm trying to tweak my MySQL config on my Magento 1.9 install, without Full Page Cache installed on the server it run's really slow and I'm pretty sure its something to do with the MySQL Config.
Could you take a look at my, my.cnf file and share some recommendations - I've run mysqltuner.pl and I'll share this information too:

General recommendations:
Control warning line(s) into /var/log/mysql/error.log file
Run OPTIMIZE TABLE to defragment tables for better performance
OPTIMIZE TABLE `db_db.log_visitor`; -- can free 66 MB
OPTIMIZE TABLE `db_db.log_visitor_info`; -- can free 101 MB
OPTIMIZE TABLE `db_db.report_event`; -- can free 55 MB
Total freed space after theses OPTIMIZE TABLE : 222 Mb
Restrict Host for user@% to user@SpecificDNSorIp
Reduce your overall MySQL memory footprint for system stability
Dedicate this server to your database for highest performance.
Configure your accounts with ip or subnets only, then update your configuration with skip-name-resolve=1
Adjust your join queries to always utilize indexes
When making adjustments, make tmp_table_size/max_heap_table_size equal
Reduce your SELECT DISTINCT queries which have no LIMIT clause
Increase table_open_cache gradually to avoid file descriptor limits
Read this before increasing table_open_cache over 64: http://bit.ly/1mi7c4C
Beware that open_files_limit (1024) variable
should be greater than table_open_cache (407)
Variables to adjust:
*** MySQL's maximum memory usage is dangerously high ***
*** Add RAM before increasing MySQL buffer variables ***
query_cache_size (=0)
query_cache_type (=0)
query_cache_limit (> 1M, or use smaller result sets)
join_buffer_size (> 256.0K, or always use indexes with joins)
tmp_table_size (> 16M)
max_heap_table_size (> 16M)
table_open_cache (> 407)
innodb_buffer_pool_size (>= 7G) if possible.
innodb_log_file_size * innodb_log_files_in_group should be equal to 1/4 of buffer pool size (=3G) if possible.
innodb_buffer_pool_instances(=7)
** Server Spec **
12 CPU's
12GB Ram
Any help would be great.
