| -------- Replication Metrics ------------------------------------------------- | |
| [[0;34m--[0m] No replication slave(s) for this server. | |
| [[0;34m--[0m] This is a standalone server.. | |
| -------- Recommendations ----------------------------------------------------- | |
| General recommendations: | |
| Run OPTIMIZE TABLE to defragment tables for better performance | |
| MySQL started within last 24 hours - recommendations may be inaccurate | |
| Enable the slow query log to troubleshoot bad queries | |
| Adjust your join queries to always utilize indexes | |
| Increase table_open_cache gradually to avoid file descriptor limits | |
| Read this before increasing table_open_cache over 64: http://bit.ly/1mi7c4C | |
| Variables to adjust: | |
| join_buffer_size (> 128.0K, or always use indexes with joins) | |
| table_open_cache (> 400) | |
| innodb_buffer_pool_size (>= 1G) if possible. |
