-------- Recommendations -----------------------------------------------------
General recommendations:
Add skip-bdb to MySQL configuration to disable BDB
Run OPTIMIZE TABLE to defragment tables for better performance
Enable the slow query log to troubleshoot bad queries
When making adjustments, make tmp_table_size/max_heap_table_size equal
Reduce your SELECT DISTINCT queries without LIMIT clauses
Set thread_cache_size to 4 as a starting value
Increase table_cache gradually to avoid file descriptor limits
Variables to adjust:
query_cache_size (>= 8M)
tmp_table_size (> 32M)
max_heap_table_size (> 16M)
thread_cache_size (start at 4)
table_cache (> 64)
