The mysqltuner.pl
script gives me the following recommendation:
query_cache_limit (> 1M, or use smaller result sets)
And MySQL status output shows:
mysql> SHOW STATUS LIKE 'Qcache%';
+-------------------------+------------+
| Variable_name | Value |
+-------------------------+------------+
| Qcache_free_blocks | 12264 |
| Qcache_free_memory | 1001213144 |
| Qcache_hits | 3763384 |
| Qcache_inserts | 54632419 |
| Qcache_lowmem_prunes | 0 |
| Qcache_not_cached | 6656246 |
| Qcache_queries_in_cache | 55280 |
| Qcache_total_blocks | 122848 |
+-------------------------+------------+
8 rows in set (0.00 sec)
From the status output above, how can I judge whether or nor the suggested increase in query_cache_limit
is needed?
