-------- Recommendations -----------------------------------------------------
General recommendations:
Run OPTIMIZE TABLE to defragment tables for better performance
When making adjustments, make tmp_table_size/max_heap_table_size equal
Reduce your SELECT DISTINCT queries without LIMIT clauses
Variables to adjust:
query_cache_size (> 32M)
tmp_table_size (> 32M)
max_heap_table_size (> 16M)
innodb_buffer_pool_size (>= 48M)
