| [OK] Operating on 32-bit architecture with less than 2GB RAM | |
| -------- Storage Engine Statistics ------------------------------------------- | |
| [--] Status: -Archive -BDB -Federated +InnoDB -ISAM -NDBCluster | |
| [--] Data in MyISAM tables: 7B (Tables: 1) | |
| [--] Data in InnoDB tables: 312M (Tables: 44) | |
| [!!] Total fragmented tables: 44 | |
| -------- Performance Metrics ------------------------------------------------- | |
| [--] Up for: 1d 2h 53m 3s (109K q [1.130 qps], 11K conn, TX: 414M, RX: 7M) | |
| [--] Reads / Writes: 43% / 57% | |
| [--] Total buffers: 58.0M global + 2.7M per thread (151 max threads) | |
| [OK] Maximum possible memory usage: 463.8M (65% of installed RAM) | |
| [OK] Slow queries: 0% (1/109K) | |
| [OK] Highest usage of available connections: 4% (7/151) | |
| [OK] Key buffer size / total MyISAM indexes: 16.0M/88.0K | |
| [OK] Query cache efficiency: 80.8% (32K cached / 39K selects) | |
| [OK] Query cache prunes per day: 0 | |

| [!!] InnoDB data size / buffer pool: 312.5M/8.0M | |
| -------- Recommendations ----------------------------------------------------- | |
| General recommendations: | |
| 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 | |
| Increase table_cache gradually to avoid file descriptor limits | |
| Variables to adjust: | |
| tmp_table_size (> 16M) | |
| max_heap_table_size (> 16M) | |
| table_cache (> 64) | |
| innodb_buffer_pool_size (>= 312M) | |
