-------- Recommendations ----------------------------------------------------- | |
General recommendations: | |
Run OPTIMIZE TABLE to defragment tables for better performance | |
Increase table_cache gradually to avoid file descriptor limits | |
Your applications are not closing MySQL connections properly | |
Variables to adjust: | |
query_cache_size (> 16M) | |
table_cache (> 400) |
