General recommendations:
Run OPTIMIZE TABLE to defragment tables for better performance
Enable the slow query log to troubleshoot bad queries
Reduce or eliminate persistent connections to reduce connection usage
Increasing the query_cache size over 128M may reduce performance
Variables to adjust:
max_connections (> 70)
wait_timeout (< 28800)
interactive_timeout (< 28800)
query_cache_size (> 128M) [see warning above]
innodb_log_buffer_size (>= 1M)
